Surrounding rock classification method and classification system

Abstract

The invention discloses a surrounding rock classification method and a classification system. The method is applied to a terminal and comprises the steps of obtaining a first instruction; based on the first instruction, calling a first surrounding rock classification table from a classification table library; acquiring a first parameter and a second parameter in to-be-classified surrounding rocks, and inputting the first parameter into a first surrounding rock classification table; inputting a second parameter into the second sub-surrounding rock classification table for analysis, and obtaining a second surrounding rock classification table by combining the crustal stress value of the to-be-classified surrounding rock; detecting whether the category of the to-be-classified surrounding rock is sensitive or not through a classification parameter value in the second surrounding rock classification table, If the category of the to-be-classified surrounding rock is not sensitive, converting the second surrounding rock classification table into a document form for output; the invention has the beneficial effects that the to-be-classified surrounding rocks are classified at any place, and the classification-based result is obtained; various surrounding rock classification methods are conveniently and efficiently adopted to classify, compare and analyze the surrounding rocks of the same tunnel section; The reliability of the classification result is greatly improved. The invention has wide application value.

Description

technical field [0001] The invention relates to the technical field of surrounding rock classification, in particular to a surrounding rock classification method and a classification system. Background technique [0002] So far, more than one hundred classification methods for surrounding rocks of underground caverns have been proposed at home and abroad, and different domestic industries require different classification methods for surrounding rocks; for foreign projects, different countries require different classification methods for surrounding rocks of underground caverns. It is difficult to be familiar with and experienced in various classification methods. [0003] At present, the surrounding rock classification table for underground caverns is: a scoring table using a paper version of a certain surrounding rock classification method. The rock classification index scoring standard grades each classification index of the surrounding rock, and then manually analyzes an...

Problems solved by technology

[0004] The traditional surrounding rock classification table only contains a small amount of information such as surrounding rock classification index scoring standards, which requires geological engineers to be familiar with and have rich experience in the classification methods used, so in fact, the classification results obtained by different geological engineers may be inconsistent; The workload of rock classification analysis and calculation is large, and the traditional classification of surrounding rock is cumbersome, time-consuming, and inefficient. Some engineers even directly use macro judgments on site to determine the classification of surrounding rocks. The classification results of surrounding rocks obtained by directly using macro judgments may not be accurate Accurate, or even wrong; the traditional surrounding rock classification table is also very unfavorable for the sensitivity analysis of the surrounding rock classification parameters and classification index values ​​to the surrounding rock category according to the site geological conditions; the traditional surrounding rock classification method cannot make the on-site surrounding rock classification work Get the real-time review of the rear reviewers in real time; it is also difficult to classify and compare the same surrounding rock to be classified by using different surrounding rock classification methods on site at the same time
