| 摘 要： | 灰岩地区溶蚀现象较为普遍,其中的溶蚀带、溶洞等不良地质现象会严重影响基础工程质量与施工进度。通过对某高速公路路基地质条件和地球物理特征的分析,采用高密度电法结合地震映像法和瑞雷面波法对岩溶发育地段进行了对比探测,根据电阻率断面图结合地震波场特征,综合分析、判断、划分出不同的岩溶类型。经过钻探验证表明,该方法在灰岩地区的应用具有实际效果和应用前景。

| Abstract: | Erosion is common in limestone regions. Erosion zones,limestone cavities greatly influence the engineering quality of foundations and can delay projects. This paper discusses the analysis of the geological conditions and geophysical characteristics of the foundation of an express highway. The development of limestone cavities in the highway foundation is accomplished using a high-density electrical resistivity method combined with seismic imaging methods and Rayleigh Wave techniques. Various limestone cavit... |
