摘要
文章以广深港铁路客运专线狮子洋隧道盾构法穿越小虎沥水道工程为例,重点介绍了过江施工过程中的风险点及重难点,并提出了盾构刀具配置、开挖面泥水压力控制及处理系统管理、背后注浆、盾尾漏浆防治等针对性技术及措施。
This paper uses the shield-driven Shiziyang Tunnel,which passes through the Xiaohuli Waterway on the Guangzhou-Shenzhen-Hongkong Passenger Dedicated Line,as an example to introduce engineering geological and hydrogeological conditions as well as their risk points,key aspects and difficulties.Meanwhile,it also presents such techniques as the configuration of shield cutters,slurry pressure control and treating system management,back grouting and prevention of grout running at the shield tail.
