摘要
瑞雷波法是一种岩土原位测试勘探方法,利用其频散性的传播速度与岩土物理力学性质的相关性可以解决诸多工程地质问题。本文主要讨论了利用瑞雷波勘探方法对高速公路路基的回弹模量、压实度和路基厚度的测试方法和技术,并以京沪高速公路某段路面为例,详述了瑞雷波法勘探技术实施过程,为该段高速公路路基质量作出了合理评价。实践表明,瑞雷波法在高速公路路基的检测中能取得显著的效果。
Rayleigh Wave is a new way of reconnaissance and check in untouched rock. It is utilizing properties of dispersed frequency and mutual properties of speeded speed and physics mechanics properties of rock that may to solve a great many problems of construction geology. This essay mainly discusses using Rayleigh Wave investi gate way to check pressure extent of expressway roadbed, ability of restoring elasticity and thicken of road surface, And take some section of Beijing to Shanghai highway as the example, has related in detail the Rayleigh Wave way exploration technology implementation process, has made the reasonable appraisal for this section of highways roadbed quality. And also. in realistic work. it already obtains obvious efficiency.
