Physical model test device and test method for simulating bearing capacity of pile foundation indoors
The invention provides a physical model test device and test method for indoor simulation of pile foundation bearing capacity, the test device comprises a model box, a sample model and a loading device, the sample model is placed in the model box, the model box is internally provided with a multi-layer soil pressure adjusting device for applying confining pressure to the sample model, and the loading device is used for loading the sample model. The sample model is composed of a soil layer model, a rock stratum model, a karst cave model, a pile foundation model and a built-in soil pressure sensor, and the loading device comprises two loading assemblies symmetrically arranged on the left outer side and the right outer side of the model box and two loading assemblies symmetrically arranged on the front outer side and the rear outer side of the model box; and axial pressure and tensile force are applied to the sample model through the loading assembly for testing. Through the specially-made loading device and the sample model, the bearing capacity of the pile foundation model under various complex conditions is simulated and tested indoors, the deformation influence of the actual environment on the pile foundation is studied, and the development condition of rock stratum cracks can be well observed after the test.
本发明提供了一种室内模拟桩基承载力的物理模型试验装置及试验方法，所述试验装置包括模型箱、试样模型以及加载装置，所述试样模型放置在模型箱内，所述模型箱内设置有用于对试样模型施加围压的多层土压力调整装置，所述试样模型由土层模型、岩层模型、溶洞模型、桩基模型及内置的土压力传感器组成，所述加载装置包括模型箱的左右两外侧对称设置的两个加载组件和模型箱的前后两外侧对称设置的两个加载组件，通过加载组件对试样模型施加轴向的压力和拉力进行试验。本发明通过特制的加载装置与试样模型，在室内模拟测试多种复杂条件下桩基模型的承载力，研究实际环境对桩基的变形影响，并在试验后能较好地观察岩层裂纹的开展情况。
