摘要：To identify water and mud inrush hazard-causing structures in tunnel effectively,an identification method combining the geological identification,geophysical prospecting and drilling was put forward based on the characteristics of geology,geophysics and revealed by drilling.The implementation process and principles of the method were proposed.Geological identification could provide water and mud inrush prior information,which could guide the implementation and interpretation of geophysical exploration.Geophysical exploration could guide drilling construction.The method was an organic combination of geological identification,geophysical exploration and drilling,which could verify and provide dynamic feedback to each other.Development regularity,distribution characteristics and precursory geological information of fault and karst hazard-causing structures were summarized and analyzed.Geophysical response characteristics under different geophysical exploration methods and revealed characteristics by drilling were provided.The characteristics could provide guidance for hazard-causing structures identification.The practice in Qiyueshan tunnel of Lichuan-Wanzhou expressway has proved that,the method can effectively identify the space distribution characteristics of hazard-causing structures,which can provide references to the tunnel water and mud inrush hazard-causing structures identification in similar engineering. © 2020, The Editorial Board of Journal of Basic Science and Engineering.
