| 摘 要： | 在工程勘察领域经常用到瑞雷波勘察,目前的主要方法是基于单炮的多道瞬态瑞雷波法,这种方法的观测方式是一维的,出来的频散曲线主要是多道计算的平均效果,勘探精度较低。本文主要系统介绍多次覆盖观测系统在瑞雷波勘察中的应用,并对这种方法的原理和观测系统详加分析。最后结合实例得出多次覆盖观测系统勘探精度较高的结论。

| Abstract: | Rayleigh wave survey is an important method in engineering investigation.The major method is Multi-channel Transient Rayleigh Wave Method based on single shot.In this method,one-dimensional observation system is used.So the resulting dispersion curves are average results of multi-channel calculation,leading to a low exploration precision.This paper briefly describes the principles,methods and the applications of multi-fold geometry in Rayleigh wave survey.Finally,the author makes a conclusion： 1]the exploration precision of multi-fold geometry is high. |
