Pile-wall combined bearing loading test device and test method
The invention discloses a pile-wall combined bearing loading test device and a test method.The pile-wall combined bearing loading test device comprises a model box and a loading device, the model box is used for loading a test soil body, the model box is composed of a detachable box body and a pile-wall combined structure, and the pile-wall combined structure and the test soil body are both located in the detachable box body; the device is used for applying acting force to a pile-wall combined structure, the pile-wall combined structure comprises double-row piles, an anti-seepage wall, a flexible connecting piece and a cover plate, the cover plate is used for fixing the positions of the double-row piles and the anti-seepage wall, and the flexible connecting piece is arranged between the cover plate and the anti-seepage wall. The pile wall combined structure and the test soil body can be stressed at the same time, and the flexible connecting pieces can play a role in releasing the force on the diaphragm wall, so that the vertical load borne by the diaphragm wall in the loading process is reduced, the service life of the diaphragm wall is prolonged, the seepage control effect of the pile wall combined structure is improved, and the test efficiency is improved. Meanwhile, the integral bearing value of the test soil body can be measured by using the flexible connecting piece.
本发明公开了一种桩墙联合承载的加载试验装置和试验方法，本发明包括模型箱和加载装置，模型箱用于装载试验土体，模型箱由可拆卸箱体和桩墙组合结构构成，桩墙组合结构和试验土体均位于可拆卸箱体内部，加载装置，用于向桩墙组合结构施加作用力，桩墙组合结构包含双排桩、防渗墙、柔性连接件和盖板，盖板用于固定双排桩和防渗墙的位置，柔性连接件设置于盖板与防渗墙之间，在加载试验时，当加载装置下压施力，桩墙组合结构和试验土体能够同时受力，柔性连接件可对防渗墙起到泄力作用，以减少在加载过程中防渗墙受到的竖向荷载，延长防渗墙的使用寿命，提高桩墙组合结构的渗流控制效果，同时也能够利用柔性连接件测得试验土体整体的承载值。
