Function-restorable bridge

Abstract

The invention provides a function-restorable bridge. The function-restorable bridge comprises a pier, a bent cap, a main girder, a first inner stop block, a second inner stop block, a first outer stop block, a second outer stop block, a first transverse self-restoring inhaul cable, a second transverse self-restoring inhaul cable and a lengthways self-restoring inhaul cable, wherein the bent cap is arranged on the upper end surface of the pier; the main girder is arranged on the upper end surface of the bent cap; the first inner stop block and the second inner stop block are both arranged on the upper end surface of the bent cap and are respectively positioned on the left side and the right side of the main girder; the first outer stop block is arranged on the upper end surface of the bent cap and on the left side of the first inner stop block, and the second outer stop block is arranged on the upper end surface of the bent cap and on the right side of the second inner stop block; the first transverse self-restoring inhaul cable is connected with the first outer stop block and the right side surface of the main girder respectively; the second transverse self-restoring inhaul cable is connected with the second outer stop block and the left side surface of the main girder respectively; the lengthways self-restoring inhaul cable is connected with the main girder and the bent cap respectively. The function-restorable bridge provided in the embodiment of the invention can effectively consume earthquake energy, and can be resorted quickly after being damaged.

Description

technical field [0001] The invention relates to the technical field of bridges. Background technique [0002] Earthquake is a sudden natural disaster with great destructive power. It can cause damage or even collapse of engineering structures, directly causing casualties and property losses; it can also induce secondary disasters such as fires and tsunamis, which seriously threatens the living environment of human beings and has a great impact on society. Since my country is located at the intersection of the Pacific Ocean seismic belt and the Eurasian seismic belt, the seismic activity is high in frequency, high in intensity, shallow in focus, and widely distributed. It is a country severely affected by earthquakes. [0003] Bridges are one of the lifeline projects. Both the Haicheng earthquake and the Tangshan earthquake have shown that bridges are the most vulnerable parts of the highway system. And bridge damage will cause more serious consequences than road damage. ...

AI Technical Summary

Problems solved by technology

And bridge damage will have more serious consequences than pavement damage

The reason is that bridges are often located in critical parts such as hubs of highway systems, and their repairability in a short period of time is often worse than that of road surfaces
