摘　　要：主要介绍了电阻率对比法和电阻率CT法在江西井冈山航电枢纽防渗墙完整性及入岩深度检测中的应用及成果,通过电阻率对比法推测墙体可能存在缺陷的位置,判断墙体的完整性,利用电阻率CT法探测入岩深度。探测结果经蓄水验证,物探成果与实际情况基本一致。The paper mainly introduces the application and achievements of resistivity contrast method and resistivity CT method in detecting the integrity and rock penetration depth of cutoff wall of Jinggangshan Navigation and Hydropower Junction in Jiangxi Province, the resistivity comparison method is used to infer the possible defects of the wall, judge the integrity of the wall, and the rock penetration depth is detected by resistivity CT method. The geophysical exploration results are basically consistent with the actual situation after water storage verification.
