综合超前预报技术在王家坝隧道中的应用

Application of Comprehensive Geological Prediction in Wangjiaba Tunnel

本文首先对综合超前预报方法进行了简单介绍,重点分析了综合超前预报法在王家坝隧道的应用。根据实际开挖过程的反馈信息表明:相较与单一的预报手段,综合超前预报法能够提高预报的精确度,同时阐述了各种单一预报方法在综合超前预报中的作用。

This paper gives a brief introduction on the comprehensive advanced prediction,which was analyzed in the application of Wang Jiaba tunnel emphatically. The feedback information of actual excavation process shows that the comprehensive advanced prediction compared with single forecasting method can improve the accuracy of forecasting,meanwhile,the feedback information expounds the role of various single forecast methods in comprehensive advanced prediction.
