摘要
物探新方法、新技术在水利工程勘察领域得到了广泛应用,解决了一系列复杂的工程地质问题,取得了良好的勘察效果。文章结合工程案例,使用可控源音频大地电磁法对引洮供水二期工程16号和31号隧洞的围岩岩性和洞身发育的断层进行了有效探测,并与施工地质编录资料进行了对比分析和研究,说明物探技术在引洮供水二期工程中的探测效果良好。
New geophysical prospecting methods and technologies have been widely applied in the field of water conservancy engineering exploration,and a series of complicated engineering geological problems have been solved.Excellent exploration results have been obtained.Engineering cases are combined in the paper.Controlled source audio-frequency magnetotelluric method is applied for effectively detecting surrounding rock lithology of Tao River Diversion Water Supply Stage II Project No.16 and No.31 tunnel as well as the fault of tunnel development.The results are compared with construction geological record data for analysis and study.It is obvious that geophysical prospecting technology has excellent detection effect in Tao River Diversion Water Supply Stage II Project.
