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.

Deformation and control simulation test system for tunnel engineering supporting structure

The present invention relates to microbiology technology field. More particularly, it relates toMBR CGMCC 2318 which has the ability to reduce and adsorb metal and nonmetal ions. It also relates to methods of bioreduction and biosorption using the said strain by means of its property of reducing nitrate to ammonium and adsorbing metal ions to reduce the metal and nonmetal ions in the solution to elementary state under aerobic conditions. The present invention also relates to application of the said strain in bio-metallurgy, production of metal and nonmetal elementary substance, treatment of wastewater containing metal ions, and removal of harmful metal and nonmetal ions contained in soil and water. The strain of the present invention is easy to cultivate. The method of bioreduction and biosorption by it is very simple and can be widely used in metallurgy, treatment of wastewater and removal of harmful substances in soil and water.
