【摘要】 以重庆梁忠高速礼让隧道岩溶段为工程背景,采取"地质分析、物探预报与钻孔验证"相结合的综合预报原则,运用地质编录、AGI及TSP、瞬变电磁法、地质雷达法、超前水平探孔等手段,相互弥补与验证,建立岩溶隧道施工期综合超前地质预报体系,对礼让隧道岩溶段综合超前预报成果进行解释及分析。礼让隧道岩溶段出水出泥及破碎带的准确预报,对类似工程具有一定的借鉴与指导意义。更多还原

【Abstract】 On the background of karst section in Lirang Tunnel engineering project of Chongqing’ s Liangzhong highway,with the comprehensive forecast principle consisting of geologic analysis,physical exploration and drilling verification,using advanced forecast methods including geologic logging,AGI,TSP,TEM,GPR and advanced horizontal borehole inspection are adopted to build the comprehensive advanced geologic forecast system for the construction period of karst tunnel for explaining and analyzing the related forecast results of Lirang’ s karst tunnel section.The accurate forecast of karst section outflow and crush belt for Lirang Tunnel is expected to have referential and instructive meaning to other similar construction projects.更多还原
