A high water pressure crack rock body seepage test platform

Abstract

The invention discloses a high-water fracturing rock mass seepage test platform, comprising a data acquisition module, a storage module, a coupling analysis module, an error analysis module, a data analysis module, and a test output module. The received model data is sent to the storage module for storage. The data analysis module performs classification, stress analysis, temperature analysis and seepage analysis on the construction data, and obtains the data analysis results. The parameters of the specimen are selected, and the test data is obtained through the test of the specimen. The coupling analysis module analyzes the test data, and the test output module outputs the analysis results of the rock mass seepage in high water pressure fractures. Through the coupling analysis To obtain the seepage law of high water pressure surrounding rock in the actual tunnel, the occurrence rate of water and mud inrush disasters is reduced, and the safety of tunnel construction is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a high water pressure fracture rock mass seepage test platform. Background technique [0002] In the process of tunnel construction, the stability of surrounding rock, underground water inrush and lining water pressure are the main factors related to the success of tunnel construction. Safety, the key factor restricting the progress and cost of the project, is different from the traditional soil seepage, the rock mass seepage in the fractured rock mass medium has its own special regularity. Safety is of great significance, and the permeability coefficient of fractured rock mass is sensitive to the influence of stress; in the existing technology, many scholars have used theoretical research, numerical simulation, laboratory test and model test to conduct high-water fracturing rock mass seepage field. For example, a mathematical model considering the coupling analysis o...

[0003] However, during the excavation process of the tunnel, the natural rock mass has its own complex structure, and the movement of the fluid is also difficult to predict. The disturbance of the tunnel construction will change the original in-situ stress field, seepage field, and a large number of cracks will be generated in the surrounding rock. At the same time, the original micro-cracks will further develop, leading to the deterioration of rock mass performance. Although the existing test system and mathematical model have some research on the fractured medium, a single test model and numerical analysis results are not enough to cover all Due to the influence of uncertain factors, the seepage mechanism of fractured rock mass has not been fully understood. It is still necessary to do more detailed theoretical research on the seepage field of fractured rock mass under high hydraulic pressure to grasp the seepage mechanism of the fractured medium and deepen the understanding of the seepage in the tunnel. The evolution law of water and mud inrush damage seepage caused by high hydraulic pressure fractured rock mass seepage, in order to reduce water and mud inrush disasters in tunnel construction, for this reason, we propose a high hydraulic pressure fractured rock mass seepage test platform
