摘　　要：在层状介质中 ,瑞雷波具有频散特性。瑞雷波波速主要与其穿透深度范围内的介质物理性质有关。利用瑞雷波波速与剪切波波速的相关性可以进行岩土力学参数测试 ,但传统的瑞雷波勘探方法有一定的局限性。本文发展了多道瞬态瑞雷波勘探技术 ,从测量仪器选择、观测系统设计、数据采集与处理等方面进行了研究 。R wave has characteristic dispersion in layered media. R wave velocity is mostly relative to the nature of media in which wave can penetrate. Based on the close relationship to S wave, R wave can be used to measure geotechnical features. There are some limitions in the early exploration method of R wave. This paper developed the multichannel transient R wave exploration technology. We have carried out a lot of experiment on instrument selection, measurement system design, data collection and processing. In geotechnical engineering survey and evaluation of foundation treatment we have achieved good results in practice.
