Jiaxing-Shaoxing Sea Bridge
The Jiaxing-Shaoxing Sea Bridge (), sometimes shortened to Jiashao Bridge, is the world's longest and widest multi-pylon cable-stayed bridge. From end to end, it stretches across the Qiantang River estuary, at Shaoxing, Zhejiang, China. The main bridge is long and wide and carries an expressway with eight traffic lanes. Construction started December 2008, and the toll bridge opened for traffic on July 20, 2013. Jiashao is the second sea-crossing bridge built in the greater Hangzhou Bay area. It is about west of the longer Hangzhou Bay Bridge, which opened May 2008, a half year before construction began on the Jiashao. Design As with the Hangzhou Bay Bridge, the design of the Jiashao had to take into account the raging tidal bore and swift current of the Qiantang River estuary. To roll with the famous Qiantang tidal bore and to reduce the construction risks under difficult hydrologic conditions, the substructure foundation design for the southern and northern bridge approa ...

Qiantang River
The Qiantang River, formerly known as the Hangchow River and alternatively romanised as the Tsientang River, is a river in East China. An important commercial artery, it runs for through Zhejiang, passing through the provincial capital Hangzhou before flowing into the East China Sea via Hangzhou Bay south of Shanghai. Its original name, the "Zhe River" or "Zhe Jiang", is the origin of the name of Zhejiang province. The river is also known, along with Hangzhou Bay, for having the world's largest tidal bore, a phenomenon where leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current. Etymology Its upper stretch near the AnhuiJiangxi border is also known as the Xin'an River (, "Newly Peaceful"); its middle stretch through the mountains of Zhejiang is also known as the Fuchun River (, "Abundant Spring River"); and the former name of its lower stretchthe Zhe () or Crooked Rivergav ...

Bridges In Zhejiang
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 the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Bridges In The World
This list of tallest bridges includes bridges with a structural height of at least . The of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water. Structural height is different from , which measures the maximum vertical distance between the bridge deck (the road bed of a bridge) and the ground or water surface beneath the bridge span. A separate list of highest bridges ranks bridges by deck height. Structural height and deck height The difference between tall and high bridges can be explained in part because some of the highest bridges are built across deep valleys or gorges. For example, (as of 1 July 2020) the Duge Bridge is the highest bridge in the world, but only the eleventh tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Longest Cable-stayed Bridge Spans
This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another, it does not mean that the bridge is the longer from shore to shore, or from anchorage to anchorage. However, the size of the main span does often correlate with the height of the towers, and the engineering complexity involved in designing and constructing the bridge. Cable-stayed bridges with more than three spans are generally more complex, and bridges of this type generally represent a more notable engineering achievement, even where their spans are shorter. Cable-stayed bridges have the second-longest spans, after suspension bridges, of bridge types. They are practical for spans up to around . The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its span, has the longest span of any cable-stayed bridge, disp ...

Millau Viaduct
The Millau Viaduct (french: Viaduc de Millau, ) is a multispan cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near (west of) Millau in the Aveyron department in the Occitanie Region, in Southern France. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. it is the tallest bridge in the world, having a structural height of . The Millau Viaduct is part of the A75–A71 autoroute axis from Paris to Béziers and Montpellier. The cost of construction was approximately € 394 million ( $424 million). It was built over three years, formally inaugurated on 14 December 2004, and opened to traffic two days later on 16 December. The bridge has been consistently ranked as one of the greatest engineering achievements of modern times, and received the 2006 Outstanding Structure Award from the International Association for Bridge and Structural Engineering.

Pile Cap
A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the deep foundation of a building, typically a multi-story building, structure or support base for heavy equipment, or of a bridge. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence. Design Construction The mat is made of concrete which is an aggregate of small rocks and cement. This mixture has to be supported by a framework to avoid sagging and fracture while setting. This process is known as shuttering and reinforcing. The materials used are long steel bars with longitudinal protrusions between the piles held in shape by thinner tie wires. Once this steel mat is laid, timber is attached around the perimeter to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hangzhou Bay Bridge
Hangzhou Bay Bridge () is a long highway bridge with two separate cable-stayed portions, built across the mouth of Hangzhou Bay in the eastern coastal region of China. It connects the municipalities of Jiaxing and Ningbo in Zhejiang province. Construction of the bridge was completed on June 14, 2007, and an opening ceremony was held on June 26, 2007. The bridge was opened to public May 1, 2008, after a considerable period of testing and evaluation. The bridge shortened the highway travel distance between Ningbo and Shanghai from to and reduced travel time from 4 to 2 hours. At in length, Hangzhou Bay Bridge was among the ten longest trans-oceanic bridges. It is not to be confused with "Outer Hangzhou Bay Bridge", a project under study which would ring the bay islands between Shanghai and Ningbo. An official name does not yet exist, hence the terminology clash. History The bridge across the Hangzhou Bay was the subject of various feasibility studies for over a decade before ...

Hangzhou Bay
Hangzhou Bay, or the Bay of Hangzhou (), is a funnel-shaped inlet of the East China Sea, bordered by the province of Zhejiang and the municipality of Shanghai, which lies north of the Bay. The Bay extends from the East China Sea to its head at the city of Hangzhou, from which its name is derived. At Hangzhou, the Qiantang River flows into this Bay, providing freshwater from the West while seawater comes in from the East. Thus, Hangzhou Bay, especially its western end, is sometimes called in the scientific literature as the Qiantang River Estuary. At the southeast end of Hangzhou Bay, off Ningbo, are many small islands that are collectively called the Zhoushan Islands. This archipelago of islands is urbanized with the administrative status of a prefecture-level city in Zhejiang Province. At less than 15 meters in depth, the entire Bay is relatively shallow. Consequently, the main port in the Bay area is the one in Ningbo and Zhoushan, at the southeast end of the Bay on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
