Abstract

The invention discloses a real-time monitoring system and method for visualizing two-dimensional fracture network rock mass seepage dynamics; laying a two-dimensional fracture network rock mass in the second experimental area, and covering the second sealing cover; realizing overall hydraulic loading or partial hydraulic loading according to test requirements Hydraulic loading; connect the water volume monitoring device with the computer to monitor the water volume in real time; color the water body, carry out overall hydraulic loading or local hydraulic loading on the water body according to the test requirements, and observe the flow path of the water body in the two-dimensional fracture network under different conditions and Changes in the fracture network; According to the water volume and the final total water flow of the water body from different fracture paths recorded by the water volume monitoring device at different times, the flow law of the water body in the two-dimensional fracture network is obtained. It can be used to simulate different hydraulic loading conditions, observe the flow path of water in the two-dimensional fracture network and the change of water volume in different paths in real time, reveal the flow law of water in the two-dimensional fracture network, and is beneficial to the study of the flow law of groundwater in actual engineering .

Description

technical field [0001] The invention relates to the field of similar model tests, in particular to a real-time monitoring system and method for visual two-dimensional fracture network rock mass seepage dynamics. Background technique [0002] A large number of tunnels in our country are built in water-rich fissure rock mass, which can easily cause sudden water inrush and landslide disasters during construction. Scholars in our country have carried out a lot of research work, but there are obvious shortcomings. Most of the model tests focus on the process of water inrush, and there are few model tests to study the flow path of fracture water, and so far no real-time observation test system that can display the flow path of fracture water has been found. Existing test equipment cannot achieve local or overall loading of water bodies. In actual engineering, the study of the flow path and flow law of fissure water has extremely important theoretical value and effect on the mech...
