孔间电磁波CT技术是工程勘探中的一种常用方法，利用孔间层析成像进行探测，其成果清晰、直观，较好地展现了孔间介质电磁波吸收情况，清楚地显示出地下不同地质体的空间分布。北京普安店地区存在岩溶塌陷，前期进行了大量的钻孔勘探，利用钻孔进行孔间电磁波CT扫描，探测钻孔之间溶洞的分布情况，填补了钻孔之间溶洞展布情况的空白，并对溶洞的充填情况进行解释。该技术提供的数据准确可靠，信息丰富，为后期岩溶地区的稳定性评价及工程处理提供了科学依据和基础数据。

Cross-hole electromagnetic CT technology is a normal geophysical prospect method in engineering. The method is basis on tomographic technology. The result will gain a simple and visual map,which fully displays the cross-hole electromagnetic signal attenuation. The result shows different rocks and soil areas clearly. The karst caves are developed under the ground in Beijing Puandian. Many explored drills have been finished, after the cross-hole electromagnetic CT scanning, the karst caves were located exactly, which data may fill the blanks between the drills, and infer the karst cave fillings. The technology gains true position data and other information of the underground karst cave. For the later stability evaluation and engineering treatment, it takes basal data and scientific foundation.
