Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a multi-means advanced detection method for water-rich karst tunnels. Background technique [0002] At this stage, my country has achieved remarkable construction results, and the material demand in various regions is also increasing. However, the lack of road transportation capacity and transportation costs will hinder the development of regional economy. In the southwestern region of my country, the terrain is complex. In order to reduce costs while protecting the environment, tunnels are used for construction in mountainous areas. Therefore, tunnel engineering has become an indispensable key project in engineering construction. [0003] During the construction of the tunnel project, there are many complex geological situations. With the emergence of more and more geological structures of water inrush and mud inrush, the safety of tunnel construction is strictly restra...
