摘要
文中针对某地铁深基坑,设计了一套监测方案,分析了桩顶及其水平位移的变化。通过对桩顶和桩身水平位移的现场实时监测,并结合监测数据,分析了深基坑支护结构的位移规律。随着开挖支护和主体施工的推进,桩身最大水平位移逐渐下降,且最大位移出现在0.684 H左右。
This paper takes one subway deep foundation pit as an example,a monitoring plan for the foundation pit has been developed;In addition,through real-time on-site monitoring of the horizontal displacement of the pile top and pile body,combined with monitoring data,the displacement law of the deep foundation pit support structure was analyzed.With the advancement of excavation support and main construction,the maximum horizontal displacement of the pile body gradually decreases,and the maximum displacement occurs around 0.684 H.
