Model test device and test method for pile foundation bearing capacity during fault zone dislocation
The invention discloses a model test device and test method for pile foundation bearing capacity during fault zone dislocation. The test device comprises a first rock-soil layer and a second rock-soillayer, a fault zone is arranged between the first rock-soil layer and the second rock-soil layer, the fault zone is filled with a filler, pile foundations are buried in the first rock-soil layer andthe second rock-soil layer correspondingly, a bearing body is arranged at the lower end of the first rock-soil layer, a lifting table is arranged below the second rock-soil layer, a lifting device used for driving a lifting table top to move up and down is arranged in the lifting table, and the second rock-soil layer and the movable lifting table top are connected through a plurality of elastic pieces. A spring and the lifting table are combined, the earthquake vibration process is simulated through the spring, the lifting table is used for accurately controlling the relative displacement of the rock-soil layers on the two sides of the fault zone, and thus a model test is closer to the actual situation.
本发明公开了一种断裂带错动时桩基承载力的模型试验装置及试验方法，试验装置包括第一岩土层和第二岩土层，所述第一岩土层和第二岩土层之间设置有断裂带，所述断裂带中填充有填充物，所述第一岩土层和第二岩土层中均内埋有桩基，所述第一岩土层下端设置有承载体，所述第二岩土层下方设置有升降台，所述升降台内置用于带动升降台面上下运动的升降装置，所述第二岩土层和动升降台面通过多个弹性件连接。本发明将弹簧和升降台相结合，利用弹簧来模拟地震振动过程，使用升降台来精准控制断裂带两边岩土层的相对位移，使模型试验更加贴近实际情况。
