Abstract

A site effect simulator, including a site effect simulator base plate, where counter-force pillars are vertically arranged at diagonals of the site effect simulator base plate, the counter-force walls are connected to counter-force pillars along two sides of the site effect simulator base plate, a plurality of single-layer soil boxes are arranged at the inner side of the site effect simulator base plate, wave-absorbing materials are arranged inside single-layer soil boxes, and sliding panels are arranged at an upper side and a lower side of each single-layer soil box. The present disclosure does not need to rely on other counter-force frames, has the characteristics of flexible use, and can be randomly placed, and the height can be adjusted randomly. With a servo hydraulic actuator with three directions and six degrees of freedom, seismic simulation tests can be realized independently.
