Abstract

The invention provides a protolith structural surface manufacturing method and device and a protolith structural surface, and relates to the field of rock mechanics. The protolith structural surface manufacturing method comprises the steps of scanning a protolith structural surface sample to generate a sweep surface; carving the protolith structural surface sample according to the scanning hook face to obtain the protolith structural surface. According to the protolith structural surface manufacturing method disclosed by the invention, the scanning hook face of the protolith structural surfacesample is obtained at first, and then a rock sample is carved according to the scanning hook face to obtain the protolith structural surface. Therefore, surface characteristics of the protolith structural surface are the same as surface characteristics of the protolith structural surface sample. Physical properties of the protolith structural surface are the same as physical properties of the protolith structural surface sample, so that accuracy of the protolith structural surface in a shearing test process is improved.

Description

technical field [0001] The invention relates to the field of rock mechanics, in particular to a method and a device for manufacturing an original rock structural surface and an original rock structural surface. Background technique [0002] Due to diagenesis, tectonic movement, and external forces (such as weathering, unloading, blasting, etc.), various types of structural planes are formed in engineering rock mass. The mechanical properties such as stability characteristics, strength characteristics, and deformation characteristics of rock mass are closely related to the occurrence of structural planes in the rock mass. In actual rock mechanics engineering, the research objects are basically complex geological bodies composed of structural surfaces, and disasters and accidents caused by the existence of structural surfaces are common, such as slope instability, dam foundation slippage, structural surface rockburst, etc. [0003] Using structural surface samples to carry ou...
