The invention relates to a soil body flow model test system for a large-scale vibration table experimental platform. The test system comprises a model casing and a data collecting device. The model casing is used for simulating movement of soil under earthquake load on mountain surfaces with different slopes and different friction intensities. The data collecting device comprises a computer, a high-speed camera arranged on the front face of the model casing and connected with the computer, a three-dimensional laser scanner arranged on one side of the model casing, a sensor embedded in the model casing, and monitoring cameras arranged on the lateral surface and the bottom of the model casing, wherein the sensor and the monitoring cameras are separately connected with an existing large-scalevibration table data collecting device by data wires. Compared with the prior art, the soil body flow model test system has the advantages of being convenient and automatic, being with convenient andadjustable door opening, being free of collision and swinging, and being accurate in data capturing.
