Abstract

Tunnel rock anchor rod groups are arranged on the periphery of a waste tunnel structure, a straight wall arch lining type double-reaction-force-wall frame structure is embedded into an original tunnelstructure, and the tunnel rock anchor rod groups are anchored into the straight wall arch lining type double-reaction-force-wall frame structure. The straight wall arch lining type double-reaction-force-wall frame structure is composed of a reaction force bottom plate, vertical reaction force walls and a top arch ring, the anti-seismic test component is fixed on the reaction force bottom plate ofthe straight wall arch lining type double-reaction-force-wall frame structure, and the left horizontal jack and the right horizontal jack are hung on the vertical reaction force walls on the two sides through cable-stayed slings. A plurality of steel structure counter-force beams are arranged at the top of a vertical counter-force wall, a plurality of steel structure small stand columns are arranged between the steel structure counter-force beams and a top arch ring, a vertical jack is placed on an anti-seismic test component, the vertical jack transmits force to the steel structure counter-force beams, a horizontal jack is started, and a low-cycle repeated horizontal load test is conducted. The device has the advantages of simple structure, high construction speed, energy conservation, environmental protection, large tonnage of a horizontal load test, low cost and the like.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a reaction wall structure, in particular to a tunnel lining type double reaction wall structure device and a preparation method for earthquake resistance tests. Background technique [0002] Using the reaction wall structure, the horizontal low cycle repeated horizontal load test method is the main method for the experimental research on the seismic performance of building structures, which can obtain the seismic performance indicators such as hysteresis curve, skeleton curve, ductility coefficient, energy dissipation capacity and restoring force characteristics. Thus, the seismic performance evaluation of the building structure is carried out. [0003] To carry out the seismic performance test of a large-scale building structure model or a full-scale component, a large-scale reaction wall must be used as a support. Using a large-scale reaction wall can carry out two-dimensional ps...
