摘要
本文针对贵南高速铁路隧道工程岩溶发育、分布广、段落长、建设风险高的特点,在总结传统岩溶隧道防排水问题基础上,研究提出了一种适用于复杂岩溶地区的底板型箱体排水新型衬砌结构,可有效降低复杂岩溶地区隧道工程的水害风险。
In view of the high construction risk caused by the well-developed karst,wide karst distribution,and long karst section in the tunnels of Guiyang-Nanning High-speed Railway,a new lining structure with floor box drainage suitable for complex karst areas is proposed on the basis of summarizing the waterproof and drainage problems of traditional karst tunnels,which can effectively reduce the water disaster risk of tunnels in complex karst areas.
