Description
Technical Field
The invention relates to the field of geomechanical model tests, in particular to a sliding fracture physical simulation device.
Background
The crustal stress state is key basic data of stability evaluation of underground engineering, underground energy development and nuclear waste disposal, and has important significance for understanding of the earth dynamics process and evaluation of earthquake risk. In rock mass engineering, due to the action of tectonic stress, the rock mass will produce some deformation or fracture, and further produce such as fold, fracture and the like, and the sliding fracture is one of the most important tectonic traces of the earth crust. The fracture surface of the sliding fracture is generally flat and smooth and is nearly vertical to the horizontal plane, and when rock masses on two sides of the fracture move relatively along the trend of the fracture surface under the action of tectonic stress, a tensile stress region and a compressive stress region are formed around the fracture. This effect is slow over time if the fault produces a slow creep deformation, and is sudden and short if the fault produces a stick-slip. How does this change affect the local stress state of the fault, what does this change correlate with the activity of the fracture? Therefore, it is important and necessary to research the evolution law and fracture mobility of the local stress field of the sliding fracture.
In the research of the rock stress field, research methods such as numerical simulation, physical simulation and field monitoring are generally adopted, wherein the sliding fracture physical simulation mainly adopts a physical model which accords with a certain similar relation with a geological prototype to simulate the tectonic stress environment and the stress state of the fractured geological prototype, and the formation and evolution process of tectonic trails is reproduced, so that the evolution mechanism and the change rule of the local stress field of the geological body under the action of tectonic stress are disclosed, and the method has important significance for the research of fault stress field evolution and fracture activity.
At present, some test devices for performing physical simulation on sliding fracture exist. For example, patent publication No. CN201383278Y is a device for simulating and demonstrating slip fault dislocation, which can simulate and demonstrate slip earthquake dislocation, but cannot realize the multi-angle fracture prefabrication and bidirectional loading process of physical simulation of slip fracture. For example, patent publication No. CN206312488U realizes a visual simulation of the formation process of the slip layer by means of physical simulation, but it cannot perform prefabrication of the existing slip layer in advance and simulate the loading fracture process thereof.
