Cross-fault earthquake pseudo-dynamic test soil box and test device

The utility model discloses a cross-fault earthquake pseudo-dynamic test soil box and test device, the test device comprises a test soil box and two vibration tables, the test soil box comprises a box body, a flexible sealing piece and a vertical supporting piece, the box body comprises two half box bodies, the two half box bodies are arranged on the two vibration tables side by side, and the flexible sealing piece is arranged on the two half box bodies. And a certain distance is formed between the soil bodies to serve as a space for mutual vibration of the soil bodies on the two sides. And the flexible sealing piece is arranged at the gap between the two half box bodies, so that a good sealing effect on the gap can be achieved. The vertical supporting pieces cover the flexible sealing pieces, the soil body in the box body is supported, and it is avoided that the flexible sealing pieces in the gaps are excessively deformed under the gravity effect of the soil body, and consequently the soil body leaks out.
