摘　　要：注浆加固目标层的定位是制定地面区域治理方案时考虑的关键问题之一,不仅要使隔水层厚度满足突水系数的要求,同时还要选择岩溶裂隙相对发育、可注性较强的层段,注浆时浆液才能充分扩散。地球物理测井方法常用于钻孔剖面的岩性分层,判断含水层、岩溶发育带及确定水文地质参数等,运用多种测井技术对比分析,配合钻孔取芯和水文观测资料,可为地面区域治理目标层准确定位提供依据。The positioning of the target layer for slurry reinforcement is one of the key issues to be considered when formulating the surface area treatment plan.It is not only necessary to make the thickness of the water barrier meet the requirements of the sudden water coefficient,but also to select the layer section with relatively developed karst fissures and strong injectability so that the slurry can be fully diffused during the injection.Geophysical logging methods are often used for lithological stratification of borehole profiles,determination of aquifers,karst development zones and hydrogeological parameters,etc.The use of multiple logging techniques for comparative analysis,together with borehole coring and hydrological observation data,can provide a basis for accurate positioning of the target layer for regional management on the ground.
