Surface wave prospecting technology is a new method in the engineering groundwork survey. This paper studies the surface wave prospecting technology to solve the boundaries between pond sludge and artificial fill-soil (rock) and the imbedding depth of artificial fill-soil (rock). The results show that geological drilling and other data can compensate the shortcomings of the single transient surface wave method used and improve the ability to recognize the geophysical anomaly. The result of surface wave prospecting has provided accurate and detailed fundamental information about the filling sea area and showed the desired effect.
