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的结论 。
Ground settlement is motivated by variable factors. This article describes the actual conditions of the ground settlement monitoring in the running tunnels of Gongyuanqian Station-Haizhu Square Station of Guangzhou Metro Line 2, which was constructed by underground cutting method with shallow overburden; analyzes the primary causes of ground settlement; summaries the accessorial technical measures, e.g. timely strengthening the initial support and variable grouting during tunneling, taken to control the ground settlement. It is useful for theoretical research and application preference.
