摘要
文章主要介绍宜万铁路大支坪隧道F5富水断层综合超前地质预测预报技术的实例应用,采用TSP203物理探测、地质雷达探测和水平超前探孔验证等手段,探明该断层水文地质、岩溶发育规模等地质特征,取得了明显的效果,为下一步施工方案制定及隧道结构优化设计提供了可靠的地质资料。
The paper briefly introduces the application of comprehensive geological prediction for the watersoaked fault F5 in Dazhiping Tunnel on Yichang-Wanzhou railway.TSP geophysical exploration,geologic radar exploration and horizontal advance exploration drilling were used to explore the geological characteristics,including hydrology and the development scale of the karst with efficient results acquired,reliable geological data were obtained for the construction option and optimization of structural design.
