Description

technical field [0001] The invention relates to the technical field of geological detection, in particular to a systematic construction method for advanced forecasting of water gushing in karst tunnels. Background technique [0002] With the acceleration of the construction of highway tunnels in our country, complex geological conditions are often encountered during the construction of highway tunnels. Due to the existence of a large number of karst geology in Southwest my country, the tunnel construction has brought great construction difficulties and increased construction risks. Especially in limestone areas where karst is developed, tunnel construction has a higher probability of exposing karst caves, and the resulting damage will be greater. If it is a large-scale water-rich cave, it may cause serious damage to construction personnel and mechanical equipment in an instant, resulting in unpredictable consequences. If it is mild, it will cause the extension of the const...
