BEAM地质超前预报系统在锦屏引水隧洞TBM施工中的应用

The Application of the Beam Geological Advance Prediction System for the TBM Construction of the Jinping Diversion Tunnel

BEAM系统作为一种新型的电法超前地质预报技术,具有设备简便、易于操作、可实时准确探测并显示前方地质情况等特点,在锦屏二级水电站1号引水隧洞TBM401-319掘进机上应用,取得了很好的效果,值得推广应用。

As a new type of electrical geological prediction technology, BEAM system has the characteristics of simple devices, easily operating, accurately detecting and displaying the front geological conditions and others. The system has been applied to TBM401-319 in the Jinping 2 Hydropower Station No. 1 diversion tunnel and achieved very. good results. So the BEAM system should be adapted widely.
