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

The present invention proposes a function recoverable bridge, comprising: a bridge pier; a cover beam, the cover beam is arranged on the upper end surface of the bridge pier; a main girder, the main beam is arranged on the upper end surface of the cover beam; first and second inner stoppers, The first and second inner stoppers are both arranged on the upper end surface of the cover beam and are respectively located on the left and right sides of the main beam; the first and second outer stoppers, the first outer stopper is arranged on the upper end surface of the cover beam on and on the left side of the first inner stopper, the second outer stopper is set on the upper end surface of the cover beam and is located on the right side of the second inner stopper; the first and second transverse self-resetting cables, the first transverse The self-resetting stay cables are respectively connected to the first outer block and the right side of the main beam, and the second transverse self-resetting stay cables are respectively connected to the second outer stopper and the left side of the main beam; and the longitudinal self-resetting stay cables, The longitudinal self-resetting stay cables are respectively connected with the main girder and the cover girder. The function-restorable bridge according to the embodiment of the present invention can effectively consume earthquake energy, and can quickly complete the repair of the bridge after damage.
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. ...
