Method and device for detecting horizontal foundation coefficients of aeolian sand foundation
The invention provides a method and device for detecting horizontal foundation coefficients of an aeolian sand foundation. The device comprises an outer casing box and an inner embedded box which are internally provided with a displacement detection assembly, horizontally arranged and movably connected. The opening side of the inner embedded box is inserted into the opening side of the outer casing box. According to the method, horizontal load is applied on the detection device step by step successively, a load-displacement curve of relative displacement of the inner embedded box and the outer casing box is recorded and drawn, and the load-displacement curve of different depths in an exploratory well is obtained. The detection device is simple in structure and convenient to disassemble and assemble, measurement of the horizontal load-displacement full-process curve of the foundation soil which is poor in independence, such as the aeolian sand foundation is achieved, and the method and device for detecting the horizontal foundation coefficients of the aeolian sand foundation are suitable for various properties of soil. According to the method for detecting the horizontal foundation coefficients of the aeolian sand foundation, the detection process is comprehensive, precise and simple, the stress state of the test working condition and the actual load-bearing working condition of the foundation soil are made to be the same, the availability and accuracy of the detection result are improved, and safe operation of a power transmission line is guaranteed.
