Abstract

The invention provides a method for predicting water bursting and mud bursting disasters caused by penetration of a tunnel into a water-rich mylonite zone. On the basis of a seismic wave reflection method, a high-density resistivity method, a local drilling method and an electromagnetic wave reflection method, an objective of predicting water bursting and mud bursting disasters caused by penetration of a tunnel into a water-rich mylonite zone is achieved by using a time-sharing fixed-point detection method. The time-sharing fixed-point detection technology is employed and macroscopic, rapid and non-destructive properties of the geophysical prospecting means are utilized fully, and local drilling and sampling are carried out for assistance. The method provided by the invention has advantages of low cost, good time saving performance, and high rapidity.

Description

technical field [0001] The invention relates to the technical field of geophysics, in particular to a method for predicting water and mud inrush disasters when a tunnel passes through a water-rich miling rock belt. Background technique [0002] The judgment of the water and mud inrush caused by the tunnel passing through the water-rich fault structure zone is based on the accurate grasp of the geological conditions and the comparison of the mud-water pressure and the protection strength. [0003] At present, the research on the problem of mud and water inrush in engineering circles either focuses on the detection of geological conditions, or focuses on the research of the mechanism of mud and water inrush, or focuses on the evaluation of anti-outburst measures, and rarely starts from the prediction of mud and water inrush. A systemic solution is proposed from a perspective. [0004] The milingite belt is an ultra-fine-grained structural belt formed by the compression of reg...
