  • Three-dimensional non-uniform loading/unloading and steady pressure model test system
    Patent number: 10408718
    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.

  • INTELLIGENT NUMERICALLY-CONTROLLED ULTRAHIGH PRESSURE TRUE THREE-DIMENSIONAL NON-UNIFORM LOADING/UNLOADING AND STEADY PRESSURE MODEL TEST SYSTEM
    Publication number: 20190078987
    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 displace
