摘要
岩溶是高速公路、铁路等基础设施建设的重大地质隐患,用地球物理方法对岩溶进行探测是岩溶地质调查的重要手段。岩溶洞穴与其围岩之间一般存在较明显的密度、速度和电性等物理性质的差异,采用地震映像法、瞬态瑞雷面波法和高密度电法等综合物探手段对厦成高速公路瑞金至赣州段进行了岩溶地质调查。结果表明,这些方法的综合应用有效查明了灰岩地区岩溶的分布范围、埋藏深度和发育情况。
Karst is the grave geologic hidden trouble in the infrastructure construction such as expressway and railway.Geophysical prospecting is one of the important means of karst geologic survey.Karst caves are quite different from their surrounding rocks on physical properties such as density,velocity,and electrical property.This paper introduced karst geologic survey in Ruijin-Ganzhou section of Xiamen-Chengdu Expressway with comprehensive geophysical prospecting methods such as seismic imaging,transient Rayleigh wave,and 2-D resistivity imaging survey.Results show that the distribution scope,burial depth,and development conditions of karst in limestone region can be effectively delineated.
