Abstract

The invention relates to the field of civil engineering, and discloses a surrounding rock grading method, a processor and a storage medium. The method for surrounding rock grading comprises the steps: collecting the first images of a cave wall and a cave top, wherein the cave wall and the cave top are the cave wall and the cave top of a cave chamber corresponding to surrounding rock; performing distortion correction and mosaic on the first image to generate a base image; measuring the structural plane occurrence on the base map, selecting a measurement interval on the base map, measuring the volume joint number of the rock mass in the selected measurement interval according to the structural plane occurrence, and determining the integrity coefficient of the rock mass according to the volume joint number; collecting a plurality of rocks, and performing a point load test on the rocks to obtain the uniaxial saturated compressive strength of the rocks; obtaining a first quality index of the surrounding rock according to the integrity coefficient of the rock mass and the uniaxial saturated compressive strength of the rock; and determining surrounding rock classification according to the first quality index. According to the embodiment of the invention, the surrounding rock grading accuracy can be improved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method, a processor and a storage medium for grading surrounding rocks. Background technique [0002] Surrounding rock classification refers to dividing the infinite rock mass sequence into a limited number of categories with different degrees of stability according to the indicators such as rock mass integrity and rock strength. Surrounding rocks are divided into several categories. On the basis of the classification of surrounding rocks and according to the stability of each type of surrounding rocks, the best construction method and supporting structure design are given. Surrounding rock classification is the basis for selecting construction methods, and is the basis for scientific management, correct evaluation of economic benefits, determination of loads on structures (loose loads), determination of types and sizes of lining structures, and formulation of labor quotas and...
