Abstract: The paper is a case study on a slope engineering project, it applied the Raleigh wave method into the manmade high slope during construction exploration. It obtained the data on depth of the base-rock in the slope zone, the thickness of the weathering zone, the shape of the slope surface, etc. With these data, it is possible to set the bore hole in the key positions along the "main slope part", the depth of the original slope surface has been checked as well. The conclusions of this paper is:the results from wave method generally fit the bore hole results, which shows the application of the Rayleigh wave method into the exploration of construction on high slope is a practical choice.
