摘要
以津秦客运专线唐山站改造工程中南新道中桥基坑开挖为研究背景,为了加强基坑开挖中支护控制,应用大型数值分析软件FLAC3D进行了分析,得到了围护桩桩顶水平位移、侧向位移和地表沉降随开挖工况而发生变化的分布规律,指出施工中应加强监测的关键部位或区域,对实际施工具有指导意义.
Based on the bridge excavat!ion of the Tangshan station reconstruction project of Tianjin- Qinhuangdao passenger dedicated line, the large-scale numerical simulation software FLAC3D is applied to the analysis in order to strengthen the control of excavation support. The distribution regularity of the horizontal displacement of the pile head, ground settlement and lateral horizontal displacement changed with excavation are derived. The monitoring of the key points and regions should be strengthened. It is of guiding significance in construction.
