Yanghwa Bridge
The Yanghwa Bridge (양화대교) is an eight lane bridge spanning the Han River in Seoul. The bridge connects Mapo-gu on the north side of the river to Yeongdeungpo-gu on the south side of the river. The bridge is buttressed by the eastern end of the island of Seonyudo, home to Seonyudo Park (선유도공원). The bridge is a combination of two bridges: the old bridge, originally called the "Second Han River Bridge" (제2한강교), completed in 1965; and the new bridge, completed in 1982. The old bridge was the first bridge built by Korean technology after independence in 1945 and served as the gateway from Seoul to the west coast. Due to increasing traffic, construction for an expansion started in 1979 and the new eight lane bridge was completed in February 1982. The old bridge's upper structure has a width of 18.0m, length 1,053m and is composed of steel plate girders and concrete box girders. The new bridge has a width of 16.1m, length 1,053m and is a steel plate girde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bukhansan
Bukhansan (, ), or Bukhan Mountain, is a mountain on the northern periphery of Seoul, South Korea. There are three major peaks, Baegundae , Insubong , Mangyeongdae . Because of its height and the fact that it borders a considerable portion of the city, Bukhansan is a major landmark visible from most city districts. The name "Bukhansan" means "mountain north of Han River", referring to the fact that it is the northern border of the city. During the Joseon era, the peaks marked the extreme northern boundary of Seoul. Bukhansan is the highest mountain within Seoul city boundaries. Apart from Bukhansan, there are seven other mountains including Dobongsan and Suraksan that are over 600 meters high within the city. Popular throughout the year, Bukhansan, and Bukhansan National Park, which was formed in 1983, are renowned for birdwatching, hiking and rockclimbing. Bukhansan attracts a large number of hikers; around 5 million per year. Name Since 2002 there has been a movement to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Box Girder Bridge
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges. Development of steel box girders In 1919, Major Gifford Martel was appointed head of the Experimental Bridging Establishment at Christchurch, Hampshire, which researched the possibilities of using tanks for battlefield engineering purposes such as bridge-laying and mine-clearing. Here he continued trials on modified Mark V tanks. The bridging component involved an assault bridge, designed by Major Charle ...

Bridges Completed In 1965
A bridge is a structure built to 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 the origin of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Han River Bridges
The Han River or Hangang () is a major river in South Korea and the fourth longest river on the Korean peninsula after the Amnok (Yalu), Tuman (Tumen), and Nakdong rivers. The river begins as two smaller rivers in the eastern mountains of the Korean peninsula, which then converge near Seoul, the capital of the country. The Hangang River and its surrounding area have played an important role in Korean history. The Three Kingdoms of Korea strove to take control of this land, where the river was used as a trade route to China (via the Yellow Sea). The river is no longer actively used for navigation, because its estuary is located at the borders of the two Koreas, barred for entrance by any civilian. The river serves as a water source for over 12 million South Koreans. In July 2000, the United States military admitted to having dumped formaldehyde in the sewer system connected to the river, causing protests. The lower stretches of the Hangang River are lined with pedestrian wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Hankyoreh
''The Hankyoreh'' (, literally "The Korean Nation" or "One Nation") is a centre-left liberal daily newspaper in South Korea. It was established in 1988 after widespread purges forced out dissident journalists, and was envisioned as an alternative to existing newspapers, which were regarded as unduly influenced by the authoritarian government at the time. When it launched, it claimed to be "the first newspaper in the world truly independent of political power and large capital." As of 2016, it has been voted as the most trusted news organization by Korean journalists for nine consecutive years but also it is the least influential news outlet by the survey. It has online editions in English, Chinese, and Japanese. History The newspaper was originally established as ''Hankyoreh Shinmun'' () on 15 May 1988 by ex-journalists from the Dong-a Ilbo and Chosun Ilbo. At the time, government censors were in every newsroom, newspaper content was virtually dictated by the Ministry of Cul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pre ...

Plate Girder Bridge
A plate girder bridge is a bridge supported by two or more plate girders. Overview In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape rather than I-shape. The first tubular wrought iron plate girder bridge was built in 1846-47 by James Millholland for the Baltimore and Ohio Railroad. Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site. Generally, the depth of the girder is no less than the span, and for a given load bearing capacity, a depth of aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gwangbokjeol
The National Liberation Day of Korea is a holiday celebrated annually on 15 August in both South and North Korea. It commemorates Victory over Japan Day, when the United States and the Soviet Union liberated Korea from 35 years of Japanese rule. Etymology In South Korea it is known as ''Gwangbokjeol'' (; ), and is one of the public holidays in South Korea. In North Korea it is known as ''Chogukhaebangŭi nal'' (; ), and is also one of the public holidays in North Korea. The name ''Gwangbokjeol'' is composed from the Korean words 광 (gwang), meaning “light”; 복 (bok), meaning “restoration”; and 절 (jeol), meaning “holiday”. The word “restoration” is used rather than the word for “independence”, 독립 (dongnip), in order to illustrate how Korea had been a nation for centuries prior to Japanese rule. History The day marks the annual anniversary of the announcement that Japan would unconditionally surrender on August 15, 1945. All forces of the Impe ...
