Abstract: After years of operation,some risks of different degree in the earth-rock dam probably formed,and some dam maybe develop into dangerous project. Identifying cause,distribution and influence range of the hidden risks is significant to the risk elimination design and implementation. The detection methods and their effects for earth-rock dam hazard investigation and the grouting treatment effects of some projects is introduced in this paper. The arrangement,acquisition parameter setting and data analysis of common geophysical methods to detect hidden risks of earth-rock dam is presented. The significance of the comprehensive geophysical prospecting method is also expounded. The analysis could provide a reference for similar projects.
