Foundation influence simulation device under earthquake load effect

The utility model discloses a foundation influence simulation device under an earthquake load effect, which comprises an earthquake load simulation device, a simulation foundation body, a fixing system and a detection device, the simulation foundation body is a stable structure body consisting of an upper structure, a soil layer and a foundation model box, the foundation model box is fixed in thesoil layer, and the detection device is fixed in the foundation model box. Wherein the distance between the bottom of the basic model box and the earthquake load simulation device is not less than 2 meters, the upper structure is a frame structure cast in place on the basic model box, and the fixing system comprises an outer frame used for enclosing and fixing a soil layer on the earthquake load simulation device. The detection device comprises a soil layer settlement detection module arranged on the top of the basic model box and a motion and mechanical characteristic detection module arranged on the basic model box.
