摘　　要：岩溶地区轨道交通区间隧道紧邻铁路桥桥墩基础,而铁路桥施工年代久远,基础竣工资料难以考证。文章提出1种综合勘察手段,将电磁波CT与钻探、微动法相结合,对桥墩的基础型式及基础下的岩溶发育情况进行探查,不仅为隧道设计提供更为准确的依据,同时也为类似工程提供了1种可行的勘察物探一体化工作方法。The tunnel in the karst area is close to the pier foundation of the railway bridge,and the railway bridge has been constructed for a long time,so it is difficult to verify the completion data of the foundation.This paper puts forward a comprehensive survey method,which combines electromagnetic wave CT with drilling and micro motion method to detect the foundation type of the pier and the karst development under the foundation,which not only provides a more accurate basis for the tunnel design,but also provides a feasible integrated survey and geophysical exploration method for similar projects.
