Gallery Road
The historical Gallery Roads (), also known as Cliff Roads or Plank Roads, were routes traversing remote mountainous regions of China. The roads were fashioned using wooden planks securely fastened within holes carved into cliff sides. Primarily found in the Qin Mountains, they connected the Wei River and the Han River valleys. The first gallery roads were built during the Warring States period (476–221 BC) and used by Qin to invade Shu and Ba. They were fully consolidated into a thriving network during the Han dynasty. Before the 20th century, very primitive versions were used in the western gorges of the Pamir Mountains. Overview Gallery Roads were notable engineering accomplishments in ancient Chinese history. This infrastructure was predominantly constructed to ease transportive strain across cliffs in rugged mountainous areas. The Shu Road serves as a prime illustration, traversing some of China's most rugged and desolate terrains, including the Qinling and Daba ...

Chang'an
Chang'an (; zh, t=長安, s=长安, p=Cháng'ān, first=t) is the traditional name of the city now named Xi'an and was the capital of several Chinese dynasties, ranging from 202 BCE to 907 CE. The site has been inhabited since Neolithic times, during which the Yangshao culture was established in Banpo, in what is now the city's suburbs. Furthermore, in the northern vicinity of modern Xi'an, Qin Shi Huang of the Qin dynasty, China's first emperor, held his imperial court and constructed his massive mausoleum guarded by the Terracotta Army. From its capital at Xianyang, the Qin dynasty ruled a larger area than either of the preceding dynasties. The imperial city of Chang'an during the Han dynasty was located northwest of today's Xi'an. During the Tang dynasty, the area that came to be known as Chang'an included the area inside the Ming Xi'an fortification, plus some small areas to its east and west, and a substantial part of its southern suburbs. Thus, Tang Chang'an was eight t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Roads And Tracks
Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500, ending with the expansion of Islam in late antiquity. The three-age system periodises ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was exponentially increasing due to the Neolithic Revolution, which was in full progr ...

Skyway
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of Covered bridge, enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking. In North America skyways are usually owned by businesses, and are therefore not public spaces as compared with sidewalks. However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covered Bridge
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge can last over 100 years. In the United States, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration. Surviving covered bridges often attract touristic attention due to their rarity, quaint appearance, and bucolic settings. Many are considered historic and have been the subject of historic preservation campaigns. European and North American truss bridges Typically, covered bridges are structures with longitudinal timber-trusses which form the bridge's backbone. Some were built as railway bridges, using ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stone Cattle Road
The Stone Cattle Road () was an ancient Chinese road over the Qinling Mountains used by the state of Qin to conquer modern Sichuan and Chongqing in 316 BC. Story The story goes that King Huiwen of Qin on the Wei River wished to conquer the kingdom of Shu and Ba to the south over the impassable Qinling Mountains in the Sichuan Basin. Knowing of the King of Shu's fondness for treasure, he had his sculptors make five life-sized stone cows with gold tails and hindquarters with gold and placed them where the Shu ambassadors could see them. When the king of Shu heard of this, he thought it would be good to fertilize his treasury with golden cowpats, so he asked the king of Qin to send the cattle. The king of Qin replied that he was glad to do so, but the cattle were delicate and that to deliver them it would first be necessary to build a gallery road over the mountains. When this Stone Cattle Road was completed in 316 BC, he used it to invade and conquer Shu. Sage gives a sligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valley
A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally ...

Qin Dynasty
The Qin dynasty ( ) was the first Dynasties of China, imperial dynasty of China. It is named for its progenitor state of Qin, a fief of the confederal Zhou dynasty (256 BC). Beginning in 230 BC, the Qin under King Ying Zheng engaged in a Qin's wars of unification, series of wars conquering each of the rival states that had previously pledged fealty to the Zhou. This culminated in 221 BC with the successful unification of China under Qin, which then assumed an imperial prerogativewith Ying Zheng declaring himself to be Qin Shi Huang, the first emperor of China, and bringing an end to the Warring States period (221 BC). This state of affairs lasted until 206 BC, when the dynasty collapsed in the years following Qin Shi Huang's death. The Qin dynasty's 14-year existence was the shortest of any major dynasty in Chinese history, with only two emperors. However, the succeeding Han dynasty (202 BC220 AD) largely continued the military and administ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guanzhong
Guanzhong (, formerly romanization of Chinese, romanised as Kwanchung) region, also known as the Guanzhong Basin, Wei River Basin, or uncommonly as the Shaanzhong region, is a historical region of China corresponding to the crescentic graben structural basin, basin within present-day central Shaanxi, bounded between the Qinling Mountains in the south (known as Guanzhong's "South Mountains"), and the Huanglong Mountain, Meridian Ridge and Mount Liupan, Long Mountain ranges in the north (collectively known as its "North Mountains"). The central plain, flatland area of the basin, known as the Guanzhong Plain (关中平原; pinyin: Guānzhōng Píngyuán), is made up of alluvial plains along the lower Wei River and its numerous tributaries and thus also called the Wei River Plain. The region is part of the Shanxi, Jin-Shaanxi, Shaan Basin Belt, a prominent section of the Shanxi Rift System, and is separated from its geological sibling — the Yuncheng Basin to its northeast — by the ...

Piling
A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and caissons. Piles are generally driven into the ground '' in situ''; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering d ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically relief, even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form ( DEM). It is often considered to include the graphic representation of t ...
