Problems solved by technology

At present, issues such as the relationship between the overlying structure and bedrock and the influence of the form of bedrock on geological hazards are widely used in geotechnical engineering, hydrogeology, landslides, debris flows and other research fields. Due to the difficulty of 3D bedrock simulation, most In most cases, the simulation is performed by finite element simulation software, or the problem is simplified to a two-dimensional situation for simulation. However, in this way, it is impossible to verify the rationality of the theory through more accurate experiments, or it is impossible to simulate the complexity of the bedrock working conditions so that It will reduce the persuasiveness of theoretical research. In view of the lack of three-dimensional

Description

technical field [0001] The invention relates to the technical field of geotechnical simulation tests, in particular to a test device and a test method for simulating three-dimensional bedrock. Background technique [0002] Bedrock is a hard rock layer on the surface of the land, which is generally covered by soil layers and buried at different depths, ranging from a few meters to tens of meters to hundreds of meters. Bedrock is composed of one or several types of rocks in sedimentary rock, metamorphic rock, and igneous rock, and can be used as the foundation of large-scale construction projects. At present, issues such as the relationship between the overlying structure and bedrock and the influence of the form of bedrock on geological hazards are widely used in geotechnical engineering, hydrogeology, landslides, debris flows and other research fields. Due to the difficulty of 3D bedrock simulation, most In most cases, the simulation is performed by finite element simulatio...
