Problems solved by technology

However, as the scale and difficulty of tunnel engineering in rock and soil become larger and larger, the engineering problems that arise are more complex, and more and more content needs to be studied. The requirements are getting higher and higher, and the existing test equipment can no longer meet the needs of engineering practice in terms of functions, loading methods, and the range and uniformity of the strain field formed in the model. Therefore, it is urgent to develop a Tunnel and underground engineering test equipment with advanced technology and diversified functions to meet the needs of tunnel and underground engineering research

Description

technical field [0001] The invention relates to a model test system, in particular to a multifunctional model test system for tunnels and underground engineering. Background technique [0002] Model test technology is an important means to study large-scale tunnel engineering problems in rock and soil. It can qualitatively or quantitatively study the stress and deformation characteristics of surrounding rock and tunnel structures in tunnel engineering. The test results can better reflect the real engineering situation and have Wide applicability can provide reasonable parameters for the establishment of numerical calculation models and reliable comparison and reference for numerical simulation results. When studying some extremely complex engineering problems, model test technology has even become the only method. Therefore, model test technology has been widely used at home and abroad, and has played an important role in engineering research, design and demonstration. Inte...
