高密度电阻率法和被动源面波法在水库堤坝隐患辨识中的应用

针对水库堤坝隐患辨识的复杂性，对堤坝隐患辨识的时间推移地球物理探测应用进行了探讨。以某平原水库为例，为了有效辨识其堤坝隐患情况，对目标堤坝采用高密度电阻率法和被动源面波法，分别在丰水期和枯水期开展2期物探检测，结合水文和钻探成果，对堤坝物探成果进行了时移比对分析，推断堤坝隐患主要为坝基渗漏。此次成果表明时移地球物理探测在平原水库堤坝隐患辨识中具有较好的应用效果，能实现堤坝隐患发展的时移分析与追踪。

Application of high-density resistivity method and passive source surface wave method in reservoir embankment hazard identification

Aiming at the complexity of identification of hidden dangers of reservoir dams，the application of time-lapse geophysical detection for identification of hidden dangers of dams was discussed.Taking a plain reservoir as an example，in order to effectively identify the hidden dangers of its dams，the high-density resistivity method and the passive source surface wave method were used for the target dams.The time-lapse comparison and analysis of the geophysical exploration results of the dam were carried out，and it was inferred that the hidden danger of the dam was mainly the leakage of the dam foundation.The results showed that time-lapse geophysical detection had a good application effect in the identification of hidden dangers of dams in plain reservoirs，and could realize time-lapse analysis and tracking of the development of hidden dangers of dams.
