A hybrid test device for foundation pit support structure simulation, including a stuffing box, a baffle, a sand falling device, and a lifting platform system; the stuffing box includes a front panel, and a transparent panel is arranged on the front panel; one side of the baffle is connected with a Threaded rod, the other end of the threaded rod passes through the stuffing box; the shakeout device includes a support rod, a sand frame, a first shakeout plate, a second shakeout plate, and a beam. The beam is installed on the support rod, and the sand frame is installed on the beam. The first sand shakeout plate is fixedly installed at the bottom of the sand frame, and the second sand shakeout plate is movably installed between the first sand shakeout plate and the beam. The lifting platform system includes several multifunctional lifting platforms and deformed panels connected to them. The deformed panels form initial surfaces of different shapes under the action of the multifunctional lifting platform. The invention can be used for simulating the stress and strain characteristics of the soil body under different deformation conditions of the foundation pit support structure and for testing the foundation pit support.
Description
technical field [0001] The invention belongs to the field of rock and soil support structure test, in particular to a hybrid test device for foundation pit support structure simulation. Background technology [0002] In the field of rock and soil support structure, the model test of foundation pit support structure is widely used to reveal the stability of foundation pit, foundation pit reinforcement and the stress and strain characteristics of foundation pit reinforcement. Because most of the thrust simulation devices of the existing foundation pit support structure test devices can only move or rotate, and can not move in the form of curved surface, it is impossible to carry out more complex foundation pit support simulation tests; Moreover, the existing test device of foundation pit support structure can not independently measure the stress and strain of a certain area on the continuous surface inside the soil model and its influence on the earth pressure in a limited range of...
