Description

technical field

[0001] The invention relates to a tunnel lining structure model test device and test method, which is suitable for the research on the strength, deformation characteristics and safety of the lining structure under the complex boundary conditions of underground engineering, and can also be used for the combined bearing characteristics and lining of different types of linings and different grades of surrounding rocks. Indoor simulation research on cracking characteristics and internal and external water seepage characteristics. Background technique

[0002] In recent years, with the construction of a large number of water diversion projects and road projects, the application of various types of tunnels has become more and more extensive. Due to the particularity of the tunnel structure and load bearing, as well as the imperfection of design theory and calculation methods, there are still many problems. The key issues that need to be further studied and solved, ...
