复杂环境下高承压水粉细砂层盾构进出洞土体加固关键技术

摘要

以武汉市轨道交通工程6号线16标段唐家墩站-石桥站区间盾构进出洞施工为背景,详细阐述了复杂环境下高承压水粉细砂层盾构进出洞土体加固的关键技术,有效控制了盾构进出洞施工对周边构建筑物的影响,确保了周边建构筑物的安全和盾构机的安全进出洞.%Taking interval shield tunnel construction of Wuhan rail transit line 6 project 16 tenders Tangjiadun Station-Shiqiao Station as background,this paper discusses soil reinforcement technology of high pressure water fine sand layers shield tunnel in complex environment,which effectively controls the influence of shield tunnel construction on surrounding buildings,and ensures the safety of the surrounding buildings and the safety of the shield machine.
