摘　　要：电磁波CT技术以其成像精度高,成本小及操作方便的优点在岩溶勘察中应用越来越广泛。以济南市某超高层勘察为例,利用跨孔电磁波CT技术反演构建两钻孔间的地质结构图像,并结合钻孔资料对所得图像进行解译,经开挖验证,与解译结果基本一致,取得了良好的应用效果。Electromagnetic wave CT technology is more and more widely used in karst exploration due to its high imaging accuracy,low cost and convenient operation.Taking the geotechnical exploration of a super high rise building in Jinan as an example,the geological structure image between two boreholes was built by using cross-hole electromagnetic wave CT,and the image was interpreted combined with borehole data.After excavation verification,the results are basically consistent with the interpretation results,and good application effect is achieved.
