摘要
棋盘石隧道地处岩溶及断层强烈发育区,工程地质和水文地质极为复杂,存在暗河、断层、软岩大变形、岩爆等多种不良地质,隧道在掘进中随时都可能遭遇突水、突泥等多种高风险,被定为向莆铁路Ⅰ级风险隧道,因此施工阶段风险管理工作已经成为不可或缺的手段之一,对棋盘石隧道施工阶段的风险管理进行阐述。
Qipanshi Tunnel is located in Karst and faults development zone with complicated engineering and hydrogeological conditions such as underground water, faults, great deformation of soft rock and rockburst. It is marked as the I roman risky as High risks such as water inrush and mud inrush may occur anytime during the excavation. Therefore the risk man- agement is inevitable for the construction which is presented.
