摘要
通过对国内不同区域、不同等级岩溶隧道防排水措施进行归纳总结,对比分析岩溶隧道防排水设计措施的差异性。针对叙毕铁路隧道修建过程中揭示的不同形态隧底溶洞,考虑隧底溶洞的充填状态、发育深度等因素,提出采用回填处理、隧底注浆、桩板跨越等不同类型处理措施,可有效减少隧道结构变形和渗漏水的病害。
By summarizing waterproof and drainage measures of karst tunnels in different regions and at different levels in China,differences in waterproof and drainage design measures of karst tunnels are compared and analyzed.In response to different forms of karst caves below the tunnel revealed during the construction of the Xuyong-Bijie Railway Tunnel,some factors such as filling state and development depth of karst caves below the tunnel are taken into account,different types of treatment measures such as backfill treatment,grouting at the tunnel bottom and crossing with pile plates are proposed to effectively reduce structural deformation of the tunnel and water leakage.
