深基坑支护结构监测结果分析

Analysis of Monitoring Results of Deep Foundation Pit Support Structure

文中根据桩锚支护结构深基坑的特点和周围环境,进行了支护监测及分析。监测的重点是挡土墙桩的水平位移、基坑周围土体的沉降和基坑附近建筑物的沉降。分析结果表明,最大位移出现在基坑两侧的中间位置和拐角处。锚杆有效地抑制了基坑的水平位移和沉降。基坑附近建筑物的位移受开挖速度和锚固等多种因素的影响,位移具有时间效应和空间效应的特征,监测结果为安全及合理组织施工提供了可靠依据。

Based on the characteristics of deep foundation pits with pile anchor support structures and the surrounding environment,support monitoring and analysis were conducted.The emphasis of observation lies in the horizontal displacement of retaining wall piles,the settling of soil around the foundation pit,and the construction of structures close to the foundation pit.The analysis results indicate that the maximum displacement occurs at the middle and corner positions on both sides of the foundation pit.The anchor rod effectively suppresses the horizontal displacement and settlement of the foundation pit.The displacement of buildings near the foundation pit is influenced by various factors such as excavation speed and anchoring,and the displacement has characteristics of time and space effects.The monitoring results provide a reliable basis for safe construction and reasonable organization of construction.
