Inflatable strike-slip fault movement simulation device and simulation experiment method

The invention relates to an inflatable strike-slip fault movement simulation device. The inflatable strike-slip fault movement simulation device comprises a fixed disc model box and a movement disc model box, wherein soil body models are arranged in the fixed disc model box and the movement disc model box; the fixed disc model box is fixed and the movement disc model box moves relative to the fixed disc model box along the horizontal direction; vertical loading assemblies are arranged on the fixed disc model box and the movement disc model box; vertical pressure is loaded on the fixed disc model box and the movement disc model box by the vertical loading assemblies. A simulation experiment method based on the inflatable strike-slip fault movement simulation device comprises the following steps: step 1: selecting soil body confining pressure to be applied according to a soil body burying depth to be simulated and applying pre-set pressure to the soil body models through the vertical loading assemblies; and step 2: pushing the movement disc model box by a strike-slip fault movement pushing assembly to carry out strike-slip movement simulation, and observing the formation and development of a fault zone in the soil body models through soil body model observation glass, and the damages to an underground structure model.
