摘要
Abstract
In this paper,taking a complex geological tunnel in the water resources allocation project in western Chongqing as an example,the application method of Geode EM3D system in tunnel advanced prediction is studied.The geophysical interpretation signs,anomaly identification and classification are deeply analyzed.The apparent resistivity data obtained by Geode EM3D system are used to describe the geophysical interpretation signs and identification methods that reflect the lithology,water content and structural characteristics of the strata.In practical application,the distribution of faults,fold structure boundaries and water-rich strata was successfully revealed.The results show that the rigorous standardized analysis of the apparent resistivity distribution map generated by the Geode EM3D system can effectively predict and quantify the adverse geological problems that may be encountered in the tunnel excavation process,so as to provide a scientific response for the tunnel project in the face of geological risk challenges.The plan effectively guarantees construction safety and provides solid technical support for engineering decision-making.关键词
