综合超前地质预报在云景高速公路隧道施工中的应用

Application of Comprehensive Advanced Geological Forecast in the Tunnel Construction for Yunhe-Jingning Highway

隧道施工中,地质超前预报愈显重要。采用综合超前地质预报指导施工,以浙江省云景高速公路西周岭隧道施工为例,根据现场预报结果,及时调整围岩分级、设计参数及施工方法,使施工达到快速、安全的目的。

In tunnel construction, advanced geological forecast is more and more important. Comprehensive advanced geological forecast is being used to guide the construction. Taking the construction of Xizhouling Tunnel on Yunhe-Jingning Highway in Zhejiang as the example, the surrounding rock classification, the design parameters and the construction technology are adjusted in time depending on the field forecasting result for the purpose of rapid and safe construction.
