摘　　要：介绍了瑞雷波法(SASW法)的基本原理与测试方法,并通过工程实例说明SASW法在公路复合地基加固深度的检测方面以及均匀性检测方面具有良好的应用效果。地基的承载力(包括复合地基承载力)往往难于确定,本文总结了利用瞬态瑞雷波法确定地基承载力的方法及瑞雷波速度与地基承载力的经验关系式,但该关系式具有一定的局限性、地区性,建议在以后的实践应用中仍需继续积累对比资料,不断补充修正。In this paper the principle of SASW method was introduced at first ,then the effectiveness or this method in testing the reinforcement depth and uniformity of road compound foundations was showed through engineering examples. Moreover, the bearing capacity including compound foundation bearing capacity in production, which is generally difficult to determine was summarized and the experienced correlation was also established between transient Rayleigh wave velocity and bearing force in this paper, but its application was limited in different areas, It is necessary to accumulate contrast data and modify it in the future.
