Abstract:
An ultrahigh pressure true three-dimensional non-uniform loading/unloading and steady pressure model test system in which an ultrahigh pressure true three-dimensional non-uniform loading/unloading device is arranged in a combined bench counterforce device and used for carrying out ultrahigh pressure true three-dimensional loading/unloading on a test model, and an intelligent hydraulic loading/unloading and steady pressure numerical control system is connected with the ultrahigh pressure true three-dimensional non-uniform loading/unloading device via a high-pressure oil pipe; the ultrahigh pressure true three-dimensional non-uniform loading/unloading device is controlled in a digital servo manner via an input instruction of the intelligent hydraulic loading/unloading and steady pressure numerical control system to carry out ultrahigh pressure true three-dimensional gradient non-uniform loading/unloading and steady pressure control; an automatic model displacement test system automatically acquires the displacement of any part inside the model; and a high-definition multi-probe peeping system observes a cavern excavation deformation and failure process dynamically in real time.

Claim (Index 11):
The intelligent numerically-controlled ultrahigh pressure true three-dimensional non-uniform loading/unloading and steady pressure model test system according to  claim 10 , wherein the hydraulic oil way system includes step motors, oil pumps, step overflow valves, O-shaped three-position four-way electromagnetic reversing valves, electromagnetic ball valve pressure retaining valves and synchronous valves; the step overflow valve is used for adjusting the pressure of the oil ways, the O-shaped three-position four-way electromagnetic reversing valve is used for controlling the flow direction of the oil ways, the electromagnetic ball valve pressure retaining valve is used for retaining the pressure, and the synchronous valve is used for synchronous loading; the step motor starts the oil pump to pump hydraulic oil into the oil ways, the hydraulic oil enters the step overflow valve, and the PLC hydraulic numerical control system controls the step motor according to the pressure feedback information detected by the pressure detection unit in real lime to adjust the valve core of the step overflow valve to advance or retreat to reduce or increase the pressure of the oil ways, thus completing a loading/unloading process; and when the pressure of the hydraulic oil way system is changed, the PLC hydraulic numerical control system controls the step overflow valve in a servo manner to increase or reduce the pressure to realize instantaneous pressure supplement, and the electromagnetic ball valve pressure retaining valve keeps the loading system in a steady pressure state; in addition, the start pressure of the hydraulic oil way system can be reduced to 0 MPa via variable frequency debugging of the step overflow valve in combination with the stepless speed adjustment of the step motor to realize zero pressure start.
