Problems solved by technology

However, these test equipment can only simulate the stress and deformation inside the surrounding rock and the interaction law between the surrounding rock and the supporting structure during the excavation process of the tunnel, and cannot simulate the effect of underground pressure water. Water has certain difficulties. It is necessary to ensure that the simulated loading of formation pressure and water pressure are independent of each other, and that the entire test device is sealed, and that the loading plates in different directions do not interfere with each other. Compared with the case without water, the test It is more difficult, and the design of the experimental device

Embodiment Construction

[0023] The invention provides a simulation test bench for interaction among tunnel structure, surrounding rock and groundwater. It consists of four major parts: ① counterforce frame; ② hydraulic servo control loading system; ③ hydraulic loading and sealing system; ④ hydraulic loading and data acquisition computer control system. Be described below in conjunction with accompanying drawing. In Fig. 1 and Fig. 2, the composition of the reaction force frame: the integral frame 6 (including the right side plate 21 and the left side plate 24) is welded as a whole with the base 17; the front limiting plate 22, the rear limiting plate 19, The front and rear tunnel mouth baffles 13 and the top cover 2 are connected to the integral frame 6 through high-strength bolts 20, and pressure water permeable holes are arranged on the top pressure bearing plate 7; the materials of each pressure bearing plate and the integral frame are made of high-strength engineering. Type steel and steel plate...
