Abstract

The passive surface wave method can detect the shear wave velocity structure of subsurface mediums, by recording the vertical component of weak vibration on the earth's surface, and then extracting Rayleigh wave dispersion curve. This paper documents the first application of the passive surface wave method in a large-scale water resources and hydropower project. Using the passive surface wave method, we made a thorough investigation of the shear wave velocity structure over the depth of 100m underground in damsite area to achieve the mission requirements. In addition to deploying the triangular array in valley terrace area, we tried to arrange the linear array in steep slope area in the exploration. Favorable results were obtained by using the spatial autocorrelation method to extract dispersion curves. The above research shows that, due to its characteristics of strong anti-interference ability, high resolution, and less effect by site conditions, the passive surface wave method has some technical advantages compared with other geophysical methods, and has good application prospect in exploration of large-scale water resources and hydropower projects.
