Abstract: A true three-dimensional physical simulation system for the influence of fault movement on tunnel operation and a test method, including a fault movement rack system, a fault movement jacking system, and a loading and movement control system. The fault movement rack system accommodates a movement model and serves as a loading reaction device. The fault movement jacking system implements fault movement and ensures that the model is not twisted and overturned in a fault movement process. The loading and movement control system performs initial ground stress loading on the model and controls the fault movement jacking system to implement fault movement of the model. Fault movement of a deep stratum under a complex high ground stress condition can be simulated, the influence of underground fault movement on safe and stable operation of a deep tunnel is simulated, and a powerful technical support is provided for safe construction of deep engineering.

Abstract: A pressure three-dimensional non-uniform loading/unloading and steady pressure model test system has a pressure three-dimensional non-uniform loading/unloading device. The pressure three-dimensional non-uniform loading/unloading device is controlled via an input instruction of the hydraulic loading/unloading and steady pressure automatic control system to carry out pressure 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 a test model. A multi-probe peeping system observes a cavern excavation deformation and failure process dynamically in real time.
