Description

technical field [0001] The invention relates to the field of indoor test equipment for geotechnical engineering, in particular to a portable device for processing the surface topography of a structural surface of original rock and an operation method thereof. Background technique [0002] In the field environment, rocks contain structural planes, and rocks often slip along the structural planes when sliding, and the sliding surfaces have certain undulations, that is, roughness. The shear properties of the rock are related to the roughness of the surface, and the surface morphology of the rock has a great influence on the shear properties. Selecting field rocks to study its shear properties can better contrast with engineering site conditions, which is of great significance to the theory related to structural planes and the application of landslide prevention and control engineering. [0003] In order to study the effect of roughness on the shear properties, the existing tec...

AI Technical Summary

Problems solved by technology

[0003] In order to study the effect of roughness on the shear properties, the existing technology can only use simulated materials to conduct research on rock samples. The advantage of conducting simulated material tests is that the same material can be used for comparative tests. At present, there is no research on original rocks. The sampling method of the control test, for the control group of the original rock, it is necessary to make the structural surface of the original rock with the same surface morphology

The surface shape of the upper and lower walls of the original rock structural surface is easily damaged during the sampling, cutting, transportation and installation process, resulting in poor matching of the upper and lower structural surfaces, and the surface shape of the structural surface is an important factor affecting its shear strength. , will cause a large error in the experimental results
