浅埋暗挖地铁施工地层沉降监测与控制
摘要:地层沉降属多因一果。以广州地铁二号线公园前站—海珠广场站浅埋暗挖地铁区间地层沉降监测为实例,归纳分析了地层沉降的主要原因,提出了及时加强初期支护(包括超前支护)和应用注浆等辅助施工措施控制地层沉降结论,值得探讨与借鉴。
Abstract:Introducing the actual conditions of the ground settlement monitoring in the running tunnels of Gongyuanqian Station~Haizhu Square Station of Guangzhou Metro Line 2, which is constructed by underground cutting method with shallow overburden, analyzing the primary causes of ground settlement, summarizing the accessorial technical measures, e.g. timely strengthening the initial support and variable grouting during tunneling to control the ground settlement. It is useful for theoretical research and application preference.
