摘要
瑞雷波法是一种岩土原位测试方法 ,主要利用在分层介质中瑞雷面波速度的频散特性以及传播速度与介质的相关性。文章介绍了瑞雷波法在内蒙古巴新麻高速公路新麻四标巨粒土路基无损检测中的应用。根据测得的各个深度范围内的瑞雷波速 VR,分析篮派冲击压路机压实巨粒土路基的效果 。
Rayleigh wave (Rwave) method is a method for testing rocksoil in situ, which uses mainly the specific property of frequency distribution on the Rwave interface in the stratified medium and the correlation between transmitting velocity and medium. This article describes the application of Rwave method in the nondestructive detection of large granular soil subgrade of No. 4 Section of Bidding for BaXinMa Expressway. According to the tested value of velocity of Rwave within the deferent depths, V R, it analyzes the result of compaction for with Lapai impact roller, and then gives quantitatively the value of compactness.
