bridgework
The total length of Huanggang Yangtze River Bridge is about 4.0 1 km, of which the total length of highway and railway is 2.567 km, and it is designed as a double deck. The upper layer is designed as a four-lane expressway with a speed of 100km/h, and the lower layer is designed as a two-lane high-speed railway with a speed of 200 km/h.
The main bridge is a steel truss girder cable-stayed bridge with twin towers, with a span of1215m and a main span of 567m. It is the largest main span of highway-railway bridge in the world so far. Its inter-city railway, national railway tie line and expressway projects have a total investment of 8.746 billion yuan. Among them, Huanggang Yangtze River Bridge is 2.493 billion yuan.
The railway part of the bridge was jointly built by the former Ministry of Railways of China and Hubei Province, and the highway part and highway sharing part of the bridge were invested by local governments. The construction period of the bridge is 4 years, and it will be completed in 20 14. As the cross-river passage of Wuhan-Huanggang intercity railway, it takes only 28 minutes to take the intercity train from Wuhan to Huanggang after the bridge is opened to traffic.
Important significance
Huanggang Yangtze River Bridge is not only an important link connecting Wuhan-Huanghua intercity railway, Daguang Expressway and Han-E Expressway, but also a river crossing channel on the connecting line between Beijing-Kowloon Railway and Wujiu Railway. It is also an important cross-river connecting line project between Zhejiang, a province with small resources and big economy in the east, and Wuhan-Han Rong express railway in the middle.
Huanggang Yangtze River Bridge has created four world firsts:
With a span of1215m and a main span of 567m, the steel beam is the first of its kind in the world. The largest stay cable of the main bridge consists of as many as 475 parallel steel wires, which is the thickest stay cable in the world. Moreover, it can bear more than 3000 tons of tensile force, and its compressive strength and tensile strength rank first in the world. In addition, the highway-railway dual-purpose bridge has a four-lane expressway on the upper floor and a two-lane passenger railway dedicated line on the lower floor, which is an inverted trapezoid with an inclination angle of 20.35 degrees, which is also the highest in the world.
