摘　　要：物探中的面波一般认为是干扰波.从理论上研究了瑞利面波在地表介质中的分布和传播特征的基础上,认为可以利用瑞利面波对表层岩土介质进行分层.通过工程实践证明,瑞利面波在浅部的地基勘察中是一种有效的方法,在地表岩土分层等方面有比其他方法更好的效果.另外,由于瑞利面波波速和横波波速的数值上的接近,使得在一定条件下可以代替跨孔横波测量,该方法是一种值得进一步研究和推广的方法.Surface wave of geophysical prospecting is thought as Interference wave. On the basis of studying on Reyleigh surface wave distribution on the surface of earth and Propagation characteristics, it is feasible to use Reyleigh surface wave to layer surface of earth. It can be proved by engineering practice Reyleigh surface wave is effective method in shallow foundation investigation, this method is more feasible than other methods in layering earth surface. Because the wave velocity of Reyleigh surface wave is very close to that of transverse wave in the numerical value. It is can Instead of cross hole wave t under certain conditions so, this method is worth to study further
