According to the main dam leakage situation of Fengtinghe Reservoir,the leakage points and their rela-tionship with reservoir level were identified by geophysical detection.The leakage detection was conducted by multi-ple methods including high density resistivity method,transient electromagnetic method,natural electric field meth-od and ground penetrating radar method.The current quality status of main dam was demonstrated,the leakage scope was preliminarily determined,and corresponding treatment proposals were put forward,which provide techni-cal support for dam acceptance work.
