| 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,并在岩土工程勘察和地基加固处理效果评价中取得了良好的应用效果.

| Abstract: | 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. |
