Qinglan Bridge
The Qinglan Bridge () is a bridge in Wenchang, Hainan, China. It connects Qinglan Town and Dongjiao Town by crossing over the Qinglan Bay. It is long and wide. This cable-stayed bridge has two A-shaped towers that are 105.81 meters high. It has 6 lanes for automobile traffic and a 2-metre side lane at the edges for small vehicles and pedestrians. The speed limit is 80 km/h. The total investment was 595 million RMB. The bridge will also be used for transportation related to the Wenchang Satellite Launch Center. It is considered the most earthquake-resistant bridge in China, being able to handle one at a magnitude of 8.5 on the Richter scale The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 ....

Wenchang
Wenchang ( postal: Mencheong; ) is a county-level city in the northeast of Hainan province, China. Although called a "city", Wenchang refers to a large land area in Hainan - an area which was once a county. The urban center and the seat of government of Wenchang is officially known as "Wencheng Town" (), which is also colloquially referred to as Wenchang City. History Wenchang, or in local Hainanese dialect as Boon Siou, is the source of most overseas Hainanese migrants, with the majority of Thailand, Vietnam, Malaysia, Singapore, UK, Australia, USA, Canada & Europe Hainanese population having ancestral roots in Boon Siou / Wen Chang. The Wenchang dialect is considered the prestige form of the Hainanese language and is used by the island's provincial broadcasting media. It was promoted from a county to a city on November 7, 1995, and had a population of 86,551 in 1999 (estimated 2006: 115,000). Maps in the Republic of China on Taiwan continue to show Wenchang as a county part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

Wenchang Satellite Launch Center
The Wenchang Space Launch Site ( zh, 文昌航天发射场, links=no), located in Wenchang, Hainan, China, is a rocket launch site — one of the two spacecraft launch sites of Xichang Satellite Launch Center (the other site is in Xichang, Sichuan). It is a former suborbital test center. It is China's fourth and southernmost space vehicle launch facility (spaceport). It has been specially selected for its low latitude, which is only 19° north of the equator, allowing for the increase in payload necessary for launching China's future space station. It is capable of launching the Long March 5, currently the most powerful Chinese rocket. Unlike the space centers on the mainland, whose rail tracks are too narrow to transport the new five meter core boosters, Wenchang uses its sea port for deliveries. Initial launches of the CZ-5 booster from Wenchang were expected to start in 2014, one year after the intended commissioning of the Wenchang Launch Site. However, the first laun ...

Richter Magnitude Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Road Bridges In China
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which i ...

Bridges In Hainan
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces ...

Transport In Hainan
Hainan (, ; ) is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. , the largest and most populous island in China,The island of Taiwan, which is slightly larger, is claimed but not controlled by the PRC. It is instead controlled by the Republic of China, a ''de facto'' separate country. makes up the vast majority (97%) of the province. The name means "south of the sea", reflecting the island's position south of the Qiongzhou Strait, which separates it from Leizhou Peninsula. The province has a land area of , of which Hainan the island is and the rest is over 200 islands scattered across three archipelagos: Zhongsha, Xisha and Nansha. It was part of Guangdong from 1950–88, after which it resumed as a top-tier entity and almost immediately made the largest Special Economic Zone by Deng Xiaoping as part of the then-ongoing Chinese economic reform program.
