Exploration of Advanced Geological Prediction for the Double-arch Highway Tunnel in Karst Area

Xiao Yao, Bingkun Cheng, Chunwei Lin, Gengen Fu

Abstract


Combined with the construction method of a highway double-arch tunnel in the karst area, a comprehensive advanced geological prediction method combining geological radar and advanced horizontal drilling is proposed, and the comprehensive advanced geological pre- diction method is successfully applied to the construction of a highway double-arch tunnel in a karst area of Guangxi. The result of site con- struction proves that the method has a satisfactory forecasting effect.
