摘要
岩溶病害问题在我国南方分布广泛,对铁路路基的前期建设与后期的运营构成很大隐患。如何准确探测岩溶地质情况,是地质工作者甚为关注的问题,为此,采用综合物探法——高密度电法和探地雷达法,对西南某铁路路基的路堤和路堑岩溶分别进行探测,经钻孔或开挖验证,综合探测结果较为可靠。
The problem of karst disease is widely distributed in South China,which imposes great hidden risk for the early construction of railway roadbed and later operation. In this paper,how to exactly detect the karst geology is a problem concerned by geological workers. Therefore,the integrated geophysical method is adopted with high-density electrical method and ground penetrating radar method to detect the embankment and cutting karst of a railway roadbed in Southwest China. Through drilling or excavation verification,the results from integrated geophysical method are reliable.
