常规电法测量挡墙存在施工效率低的缺点，而高密度电法主要是以各种地下地质体的电性差异为基础，根据在施加电场作用下地层传导电流的分布规律，推断地下具有不同电阻率地质体的赋存情况，测量效率优于常规电法。将高密度电法用于南十里长沟主流左岸挡墙测量中，结果表明：挡墙高度约为2．3 m，墙后土体中潜水位埋深为3．1～3．8 m，挡墙体内部及内侧土体中空洞总体不发育，局部存在欠密实或空洞，挡墙厚度变化不大。高密度电法所得检测结果与地质雷达所得结果以及开挖所得结果一致，表明高密度电法应用于挡墙测量中是可行的。

Ordinary electrical method is inefficient in the measurement of retaining wall,while high-density electri-cal method has better efficiency as it is based on the electrical prop of different underground geological bodies ac-cording to the distribution regularity of conduction current of strata.Therefore it was used in the measurement of re-taining wall at the left bank of mainstream Nanshilichanggou River,and the result showed that,the height of the wall is about 2.3m,the depth of potential water level in the earth behind the wall is about 3.1 -3.8m,cavities in the retaining wall and the earth are found in partial positions but are not developed in general,the thickness of the wall does not change a lot.The result is consistent with those from geological radar and practical excavation,indi-cating that high-density electrical method is feasible to measure retaining wall.
