Abstract

The invention discloses a resistivity real-time imaging monitoring method and a resistivity real-time imaging monitoring system for a water-bursting geological disaster in a construction period of underground engineering. The method comprises a data acquisition method, a data transmission method, a data real-time inversion and imaging method and a catastrophe premonition identification and early warning method. The invention also relates to the resistivity real-time imaging monitoring system for the water-bursting geological disaster in the construction period of the underground engineering. The system consists of a data acquisition subsystem, a data transmission subsystem, a data processing (data real-time inversion and imaging) subsystem and an early warning subsystem. The invention has the advantages that: data are acquired, transmitted, inverted and imaged in real time; a real-time dynamic image of crack generation, expansion and penetration can be effectively obtained; information such as the generation position and formation process of main cracks and burst water seepage channels is obtained; a series of premonition information can be successfully obtained; and geological disasters can be forecast and timely warned.

Description

technical field

[0001] The invention relates to a real-time imaging monitoring method and system for water inrush geological disaster resistivity during the construction period of an underground project. Background technique

[0002] In recent years, with the acceleration of my country's infrastructure construction and the implementation of the energy strategy, and the rapid development of the western development process, my country has built a large number of projects such as railways, highways, hydropower and cross-basin water transfer. Quite a lot of underground projects such as long tunnels and tunnels.

[0003] These underground projects generally have the characteristics of large buried depth, long tunnel line, complex geological conditions, and developed water-bearing structures. Because it is difficult to find out all the hydrogeological conditions in the previous exploration work, the probability of encountering water inrush (inrush) disasters during excavation is g...
