A construction method of a rigid-flexible economical slope anti-seismic support structure

Abstract

The invention discloses a construction method of a rigid-flexible economical slope anti-seismic support structure, comprising a rigid support structure and a flexible support structure; the rigid support structure includes a rigid frame structure and a traditional anchor rod; the flexible support structure includes Flexible frame structures and seismic anchors. The construction methods are as follows: 1 slope repair; 2 lofting; 3 traditional bolt construction; 4 seismic bolt construction; 5 rigid frame structure construction; 6 flexible frame structure construction; 7 traditional bolt tension locking; 8 seismic bolt tension locking . The invention effectively solves the problems of the traditional passive protection structure, which has poor deformation control ability, the active protection structure has no seismic performance, is prone to anchoring failure, and the frame retaining wall is hollowed out and fractured under the action of earthquake. , The bolt stress balance adjustment, can effectively control the slope displacement, has a wide range of application prospects and significant economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of side slope reinforcement, and in particular relates to a construction method of a rigid-flexible and economical side slope seismic support structure. Background technique [0002] my country's geographical location is relatively special. It is located between the Pacific Ring Seismic Belt and the Asia-Europe Seismic Belt. As a result, earthquake-induced landslide disasters occur from time to time. [0003] The existing slope protection systems are mainly passive protection structures such as gravity retaining walls and anti-sliding pile retaining walls, and active protection structures with frame retaining walls and anchors, but both protection systems are difficult to effectively resist earthquakes. Under the earthquake state, the passive protective structure cannot effectively control the slope vibration and the deformation of the rock and soil mass, and the rock and soil mass is prone to collapse and ...

AI Technical Summary

Problems solved by technology

[0003] The existing slope protection systems are mainly passive protection structures such as gravity retaining walls and anti-slide pile retaining walls, and active protection structures with frame retaining walls and anchor rods, but both protection systems are difficult to effectively resist earthquakes.

Under the earthquake state, the passive protection structure cannot effectively control the vibration of the slope and the deformation of the rock and soil mass, and it is very easy to cause the rock and soil mass to collapse and slide

Although the active protective structure has the ability to control deformation, it does not have the anti-seismic characteristics. Under the earthquake, the stress of the anchor rod increases sharply, which will cause the anchor head to fall off, the pressure platform to be crushed, the anchor rod to break, and the anchor to be pulled out. The structure of the rigid frame retaining wall will be void, brittle fracture, etc., which will cause the failure of the active protection system
