Abstract：The overburden thickness of the river bed is deep in southwestern China,and it is important to rapidly obtain the S-wave velocity of foundation site in hydropower engineering survey.Due to its low cost and simple operation,surface wave method has been widely used to detect shallow structure by S-wave velocity.In this study,the authors used active source and passive source surface wave methods to obtain S-wave velocity on the hydropower station dam in southwestern China.The active source surface wave method conducts detection with high resolution,and the passive source surface wave method gives a deeper investigation.They have their own advantages respectively.
