Abstract
The present disclosure discloses a deformation and control simulation test system for a tunnel engineering supporting structure, including a follow-up hoisting platform, actuators, a control system. It is horizontal structure. The follow-up hoisting platform reduces the friction caused by the weight of testing sample and facilitates experimental operations. Each actuator fixed on an annular box body reaction frame can move independently through a control system in form of force control or displacement control mode, and can achieve circumferential contraction loading through its gomphodont configuration. The hinged and curved design of the cushion blocks of actuators can adapt to the circumferential contraction deformation of a test sample and maintain a close fit with them during the loading process. The present disclosure provides a good solution for physical model tests on deformation and control of tunnel engineering supporting structures including uniform loading, non-uniform loading, and long-term loading conditions.
