摘要
运用高密度电法、地质雷达以及瞬变电磁法这三种物探方法技术,对岩溶塌陷区进行勘查,查明塌陷区的范围及危险性区域,为岩溶塌陷防治工程设计提供依据。采用井间透射测井对钻孔注浆试验进行检测,为防治工程设计提供相关参数。通过这四种物探技术方法的应用,成功地圈定了采空区范围;井间透射测井数据表明:钻孔注浆在岩溶塌陷区有一定的防治效果。
High density electric method, geological radar and transient electromagnetic method were used to explore the karst subsidence area, and to find out the scope and dangerous area of the subsidence, so as to provide a basis for the design of karst collapse prevention and treatment project. Interwell transmission logging is used to detect borehole grouting test to provide relevant parameters for prevention and control design. Through the application of these four geophysical prospecting techniques, the goaf area is successfully delineated. Interwell transmission logging data show that borehole grouting has a certain prevention effect in karst subsidence area.
