The traditional detection of foundation improvement mainly depends on dynamic penetration test,drilling holes test,standard penetration test and plate loading test;nevertheless,these methods are all characterized by inefficiency and high dispersion degree,and hence can't totally reflect the detection of foundation improvement.So it is necessary to develop a fast way to detect the dynamic foundation.Based on the Garden Expo Wetlands Project,the authors gave an in-depth discussion on the transient Rayleigh wave detection method.Through the processing and analysis of a large number of Rayleigh wave data collected in this project and comparing with the in-situ test results,the authors established the correlation between Rayleigh wave velocity and in-situ test data,and studied the application effect of Rayleigh wave technology in quality testing.
