摘　　要：多道瞬态瑞利波在不均匀介质中传播时,会产生频散现象,即波速随着波长产生变化;而这变化关系跟地下地质情况之间有着内在的联系,通过对频散曲线的分析,可以对岩土的物理性质作出评价。瑞利面波勘探法对场地要求不高,方法简单快捷,易于激发和识别,有效信号能量强,广泛应用于各种工程领域。强夯法对地层的加固效果是施工中重要的一环,多道瞬态瑞利波检测技术的应用有效地实现了这一过程。There would be a frequency dispersion as the multi-channel transient state rayleigh surface wave travels in formations,the velocity would transform with the frequency and the variation is related to the geological conditions.By means of analyzing the frequency dispersion curve,the rock and soil mass could be assessed.This method does not need any high-grade field and also is easy and rapid.It's easy to be excited and be recognized.It has been used in many kinds of engineering fields.The effect of detection of dynamic compaction method is an important part in the whole construction progress,and the implication of the rayleigh surface wave solves this issue efficiently.
