Abstract

The invention discloses a method for evaluating the risk of water and mud inrush in underground engineering based on multivariate precursory information. Construct the index system; confirm the interaction law of each index among the constructed index systems, conduct attribute reduction analysis on the index system according to the geological characteristics of different projects, and establish the optimized index system; adopt the weight back analysis method and expert scoring method Obtain the weight of each index in the optimized index system, determine the parameters of each index based on engineering geological survey, and obtain the risk level of the engineering design stage; obtain the risk of the project construction stage based on the geophysical field data and force field displacement field data of on-site monitoring At the same time, the evaluation level of the design stage shall be revised.

Description

technical field [0001] The invention relates to a risk assessment method for water and mud inrush in underground engineering based on multiple precursor information. Background technique [0002] With the development of the economy, underground engineering gradually develops to the deep, among which "deep", "long" and "high confining pressure" have become new characteristics and difficulties of underground engineering. Water and mud inrush accidents in underground engineering are a major geological disaster. Once an accident occurs, the consequences are extremely serious. Although the force field, displacement field, geophysical field, and seepage field information of the surrounding rock of the project can be obtained more accurately during construction, the risk of water and mud inrush disasters is evaluated with the precursor information of a single field, and there are interpretation diversity. The phenomenon of unreasonable evaluation results has greatly troubled the d...
