摘　　要：基于附加质量法,反演瑞雷波在巨粒土路基中传播的横波波速;根据横波波速和巨粒土路基强度间的相关性得到巨粒土路基的动态回弹模量,由此评价巨粒土路基的施工质量;将瑞雷波法测得回弹模量和FWD法、承载板法获得的结果比较,结果显示由瑞雷波法评价巨粒土路基的施工质量是可行的。Based on additional mass method, the shear wave velocity of Rayleigh wave transmitted in over coarse-grained subgrade is inverted; then the dynamic elastic modulus of the over coarse-grained subgrade is obtained according to the relevance between the shear wave velocity and the strength of such subgrade, through which the construction quality thereof could be evaluated; then the elastic modulus measured by means of Rayleigh wave and the results by use of FWD and bearing plate methods are compared. The result shows that the construction quality of over coarse-grained subgrade evaluated with Rayleigh wave is feasible.
