杭州市紫之隧道工程总体设计

Overall Design of Hangzhou Zizhi Tunnel Project

紫之隧道工程全长约14.14km,线路沿西湖风景区外围敷设,含3座特长隧道及2对平行匝道。隧道地址地质条件复杂,场地狭小,且环境保护要求高。论文针对紫之隧道工程的总体设计进行具体分析,包括建设条件、隧道的平纵横布置及总体施工方案,并简述了机电和景观等附属工程设计等,为类似工程提供参考。

The total length of Zizhi Tunnel project is about 14.14km.The line is laid along the periphery of West Lake scenic area,including three extra-long tunnels and two pairs of parallel ramps.The geological conditions of the tunnel site are complex and the site is small,but the environmental protection requirements are high.This paper analyzes the overall design of Zizhi tunnel project,including the construction conditions,horizontal and vertical layout of the tunnel and the overall construction scheme,and briefly describes the electromechanical and landscape design and other ancillary projects,so as to provide reference for similar projects.
