Abstract
Based on some at present advanced geophysical methods, a non-destructive detection method mainly depending on ground penetrating radar(GPR) has been established by combining with Rayleigh wave method and natural electrical field method. The quality of earth-fill dam not only can be evaluated and analyzed quickly, but also multi-method, multi-parameter, multi-information can be undertaken quantitative analysis through considering geo-technical test and geophysical information. After this method has been successfully applied to Xixia earth-fill dam detection, it is indicated that modern geophysical methods is effective to detect the diseases and faults in dam quality and this method is worthy of popularizing and application in the future.
