电磁波层析成像技术在岩溶坝基勘察工程中的应用研究

Application of Electromagnetic Image Technique in the Dam Site Investigation in Karst Terrain

根据工程实例,简要介绍了电磁波成析成像技术(CT)的基本原理,野外工作方法及其注意事项和资料解释,表明利用电磁波层析成像技术能够充分查明岩溶区坝基内隐伏溶洞岩溶、破碎带等发育规模及分布规律,为分析大坝地基稳定性分析及坝基堵漏及帷幕灌浆深度控制提供科学依据。

Throughout a case history, the basic theory of the electromagnetic imaging technique, field applications, and the key aspects of this technology are presented, The application indicates that this method can detect the underground karst rock cav ern, pinnacles and depths. The testing results can be used in the dam stability analysis as well as the curtain grouting design.
