摘　　要：传统的地基加固效果的检测方法主要是采用原位测试方法,如标准贯入试验、载荷试验、动力触探试验等,总体来说,这些方法可较直观地掌握强夯地基处理效果,但是工作效率较低,对场地环境要求较多,且离散度较高,不能对地基处理效果进行整体评价。因此,完善一种快速有效的强夯地基质量检测方法十分必要。本文以园博园湿地工程为依托,对瞬态瑞利波检测方法进行了深入探讨,通过对本工程采集的大量的瑞利波资料处理、分析,并与原位测试成果进行对比研究,给出了瑞利波速度与原位试验数据之间的相关关系,研究了瑞利波技术在地基强夯质量检测中的应用效果。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.
