该文介绍了某大型复杂岩溶场地，选择典型地段采用高密度电法、人工跑极的高密度电测深法、浅层地震、面波法、地质雷达等物探方法进行探测。经钻探和爆破开挖验证，结果表明：挖方整平区在15m深度内地质雷达探测效果较好，受施工影响最小，可在大型复杂岩溶场地施工勘察中推广应用。在溶蚀破碎带上，物探和钻探方法有时将密集发育、结构稳定的溶隙、小溶洞区域可能误判为大溶洞，在勘察中应引起注意。

In the article, several geophysical methods such as high density resistivity method , artificial ran high density electrical method, shallow seismic refraction method, surface wave method, geological radar are adopted in the typical area of large-scale complex karst site.Through the drilling and blasting excavation verified, the results show that, geological radar detection has the better effect within 15 m depth in excavation leveling area, which has little effect on construction, and it can be widely popularized and applied in the construction investigation of large-scale complex karst area;In the karst fracture zone, the solution crack with intensive development and stable structure and small cave areas were always mis -taken for large water-eroded caves by geophysical exploration and drilling method , so we should pay at-tention to these phenomena in construction investigation .
