Multifunctional test device and test method for simulating foundation load
The invention belongs to the technical field of geotechnical engineering, and particularly relates to a multifunctional test device for simulating a foundation load. The multifunctional test device comprises a test box body for containing a sample; a portal frame is erected at the upper part of the test box body; a jack is arranged on the portal frame, and is vertically arranged and is positionedin the center of the test box body; the upper end of the jack is fixed with the portal frame; the lower end of the jack is detachably connected with a cover plate; the size of the cover plate is matched with an inner cavity of the test box body; a load sensor is arranged on the cover plate; a soil layer deformation tester, a pore water pressure meter and a soil pressure meter are arranged in the sample; and the soil layer deformation tester, the pore water pressure meter, the soil pressure meter, the load sensor and the jack are electrically connected with an external controller. The device can simulate the whole treatment process of soil with various properties and different foundations, can test the development and change of rock-soil parameters of foundation treatment for a long time, can perform load test on the bearing capacity of a consolidated or reinforced foundation, and is simple in structure and intuitive and reliable in test.
本发明属于岩土工程技术领域，具体涉及一种模拟地基荷载的多功能试验装置，包括：试验箱体，用于盛装试样；试验箱体上部架设有门型架，门型架上设置有千斤顶，千斤顶竖直放置且位于试验箱体的中央，千斤顶的上端与门型架固定，其下端可拆卸式连接盖板，盖板的大小与试验箱体的内腔匹配；盖板上设置有荷载传感器，试样内设置有土层变形测试计、孔隙水压力计和土压力计，土层变形测试计、孔隙水压力计、土压力计、荷载传感器和千斤顶分别与外设的控制器电连接。本发明既能够模拟各种性质土、不同地基处理全过程，又能够实现长期测试地基处理的岩土参数发展变化，还能够对固结或加固处理后的地基承载力进行荷载测试，结构简单，测试直观可靠。
