摘要
宜(昌)至万(州)铁路岩溶极度发育,为了评价岩溶处理效果、消除隐患、保证铁路运营安全,灰岩地段的隧道及深挖路堑在工程开挖完成后必须再次进行岩溶探查。结合地质目的和现场施工条件,决定采用地质雷达、地震映像和地震面波相结合的综合物探方法进行岩溶探查,从而确保物探成果的有效性和准确性。通过对物探异常位置钻探验证,表明综合物探方法在施工后岩溶探查中是有效、可行的。
Karst is extremely developed among Yichang-Wanzhou Railway.Tunnels and deep cuttings in limestone area must be explored again to evaluate the effect of karst treatments and eliminate the hidden danger.Comprehensive geophysical exploration methods of GPR and seismic imaging and seismic surface wave are adopted to explore karst,which can ensure the efficiency and accuracy of geophysical results.Comprehensive geophysical exploration methods are proved feasibly and effectively in karst exploration after construction by drill tests in an area of geophysical anomaly.
