Abstract

The embodiment of the invention discloses an advanced detection method for a water-containing geologic structure of a tunnel, and relates to the technical field of tunnel engineering construction. Themethod can be used for detection theory study and engineering practice of the water-containing geologic structure of the tunnel to guide construction of the tunnel. The method comprises the steps ofconstructing a geologic model according to the specific variety of the water-containing geologic structure; arranging a laying-off circuit on the geologic model; receiving different geologic model condition parameters input by a user, and simulating different water-containing geologic structures; utilizing the laying-off circuit for laying off apparent resistivity values of the water-containing geologic structures under different condition parameters; drawing an apparent resistivity curve chart under the condition according to the apparent resistivity values; determining whether or not water is contained in a place in front of a working area of the tunnel according to the apparent resistivity curve chart. The method is suitable for detection forecasting and theory study analysis on the water-containing geologic structure of the place in front of the working area of the tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering construction, in particular to a method for advanced detection of water-bearing geological structures in tunnels. Background technique [0002] With the acceleration of my country's infrastructure construction process and the implementation of the energy strategy, more long tunnel (tunnel) projects will be built in the fields of transportation, water conservancy and hydropower, and mining. During the construction of these projects, they are faced with many high-risk geological disasters such as water inrush, mud inrush, and landslides. Water inrush disasters have become a bottleneck problem restricting the construction of tunnels and other underground projects. As the source of geological disasters such as water inrush, the water-conducting geological structure in front of the tunnel face has become an important problem to be studied and solved urgently. [0003] The commonly used geol...
