摘　　要：瞬态瑞雷波法是一种新兴的岩土原位测试方法 ,利用其频散特性和传播速度与地基土物理力学性质的相关性可以检测路基质量 ,本文简要介绍了利用瞬态瑞雷波法检测提速路基原理、方法及评估标准 。The instantaneous Rayleigh wave method is a new and developing geotechnical in situ test method,in which the quality of subgrade may be detected by utilizing its frequency scatter speciality and propagating speed and their relationship with the physics mechanics properties of the subgrade soil.The principle,method and evaluation standards for detecting raising speed subgrade by using the instantaneous Rayleigh wave method are introduced briefly in this paper.A practical engineering example is introduced briefly also.
