摘要
地质条件对道路的规划设计具有重要影响。文章针对实际道路工程,基于跨孔电磁波CT及剪切波测试方法对道路的岩溶地质阶段进行了地质勘探。研究结果表明,跨孔电磁波CT技术可以准确地识别出岩溶的位置,并且通过剪切波方法得出了2个钻孔的20 m等效剪切波速,分别为139.84 m/s和138.45 m/s,确定出场地类别为Ⅲ类,对类似工程具有借鉴意义。
Geological conditions have an important influence on road planning and design. In this paper,geological exploration of karst geological stage of road is carried out based on cross-hole electromagnetic wave CT and shear wave test method. The research results show that the cross-hole Electromagnetic wave CT technology can accurately identify the location of karst, and the site category is classified as ⅲ according to the shear wave test results and seismic code for Highway Engineering, which has reference significance for similar projects.
