Abstract: A true three-dimensional physical simulation system for the influence of fault movement on tunnel operation and a test method are disclosed. The system includes a fault movement rack system, a fault movement jacking system, and a loading and movement control system. The fault movement rack system is configured to accommodate a movement model and serves as a loading reaction device. The fault movement jacking system is configured to implement fault movement and ensures that the model is not twisted and overturned in a fault movement process. The loading and movement control system is configured to perform initial ground stress loading on the model and control 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 truly simulated, and a powerful technical support is provided for safe construction of deep engineering.

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.
