联合电测深法在工程勘察工作中的应用李西山（中国兵器工业勘察研究院北京１０００５３）１问题的提出在那些基岩出露、或者埋藏较浅而其产状较陡并夹有不同电性层，特别是夹有厚度较小而电阻率又较低的岩层如灰岩之中夹有簿层泥灰岩、页岩等岩层的地区；在断裂构造比较发... The Application of United Electric Sounding Method in Engineering Investigation Li Xishan (China Ordnance Industry Survey Institute, Beijing 100053) 1 The problem is suggested in those bedrocks exposed or shallowly buried and their occurrences are steep and have different electrical properties. The layers, especially those sandwiching layers of rock with small thickness and low resistivity, such as limestone, contain layers of marl and shale in the book layer;
