南水北调西线工程区活动断层CSAMT技术探测研究

APPLICATION OF CSAMT TO PROSPECTING ACTIVE FAULT

结合南水北调西线工程调水区桑日麻断裂的探测,就应用可控源音频大地电磁测深(CSAMT)进行断层深部特征的探测问题进行了分析和研究。研究结果表明,可控源音频大地电磁测深法可用于探测断层深部的发育情况,为分析工程地质问题提供基础性资料,并且可以很好地指导钻探工作的布置。

The feasibility problem of application of CSAMT to prospecting active fault in the West Route of South-to-North Water Transfer Project is studied. The study results show that CSAMT can be applied to prospect the characteristics of deep region of active fault for engineering design. Some beneficial conclusion and advice about geological prospect are obtained.
