摘要
在岩溶地区进行岩土工程勘察时,尤其要注重岩溶发育情况的探测。该文以某高铁站附近高架桥基桩区域勘探为例,着重介绍了高密度电阻率法在地下溶洞探测中的应用。采用Res2dinv软件进行反演,结合地质及钻探成果进行综合解释,获得了勘探区内溶洞的分布情况,为该高架桥安全施工提供了重要的参考依据。
The karst development detection should be pay attention especially in geotechnical engineering investigation in karst region .Taking the pile area of viaduct near a high-speed railway station for example , this paper emphatically introduces the application of high density resistivity method in detecting under -ground caves.The Res2dinv software is adopted to inversion ,combined with the geological and drilling re-sults for comprehensive introduction , the cave distribution in this detection area is obtained , and it pro-vides important reference for viaduct construction safety .
