摘　　要：某水电站大坝坝基拟建在砂卵石层上,为确定砂卵石层承载力值,采用瑞雷波勘探技术。通过测定卵石层、砂层的瑞雷波速度,再根据瑞雷波波速和承载力之间的相关关系,推测承载力,从而为确定坝基的承载力提供了依据。The dam foundation of a hydropower station is to be built on the sand and gravel layer,in order to determine the bearing capacity values on the sand and gravel layer,Rayleigh wave exploration technology is utilized.By measuring the Rayleigh wave velocities of the sand and gravel layer,and according to the relationship between Rayleigh wave velocity and bearing capacity,thence the bearing capacity of dam foundation is presumed,so it provides the basis for determining the bearing capacity of dam foundation.
