摘要

在某地面塌陷区探测中,为准确判定塌陷回填区内是否存在空洞,根据地质条件和现场状况,选用可控源音频大地电磁测深(CSAMT)和瞬变电磁法进行综合探测。对典型断面图上低阻异常特征的分析结果表明,两种探测方法结果一致,但各有特点:CSAMT法探测深度大,对异常区的判断较为准确,但分辨率相对较低;瞬变电磁法分辨率优于CSAMT,但探测深度较浅,受目标深度内介质的物性影响较大,且浅部有盲区。异常区钻孔验证结果显示,探测结果准确可靠,表明综合物探方法应用于塌陷回填区的探测是准确、有效的。

Abstract：

In the detection of a subsidence area, for the purpose of accurately determining whether there are holes in the backfill area, the CSAMT and the transient electromagnetic method shall be selected for integrated detection based on the geological and field conditions, and the analytical results show that the detecting results of the two methods are basically identical, as shown by analyzing the abnormal characteristics of the typical sectional profile, but each has its own characteristics: The depth of CSAMT method is deeper than that of TEM, and the judgment of the abnormal area is relatively accurate, the resolution of TEM is better than that of CSAMT, but the detection depth is shallow, the depth of exploration is easily affected by the physical properties of the medium within the target depth and the shallow has a blind area. The drilling through the abnormal areas of the judgement shows that the detection results are accurate, and that the integrated geophysical method is accurate and effective in the survey of collapse of backfill area.

Key words： integrated geophysical method CSAMT TEM ground subsidence geohazards investigation
