Method for preparing jointed rock mass sample and standard rock sample

Abstract

Disclosed in the present invention are a method for preparing a jointed rock mass sample and a standard rock sample, which relate to the technical field of geotechnical engineering, geological engineering, and rock mechanics tests. The method includes: blank sample acquisition first: acquiring a primary blank sample from a jointed rock mass by using a sampling device, where an outline structure of the primary blank sample is greater than that of a standard sample; integral reinforcement: immersing the primary blank sample in a penetrating liquid through vacuum-pressurized penetration treatment, and then performing curing to obtain a reinforced blank sample; and progressive grinding: mounting the reinforced blank sample in a fixture, only making a surface to be ground of the reinforced blank sample exposed, and grinding the reinforced blank sample step by step to a required size and smoothness through a grinding device to obtain the standard sample.
