深基坑周围地表沉降规律的统计分析

分析了基坑周围地表最大沉降值及其所在位置与基坑开挖深度、围护结构插入比、支撑系统刚度、抗隆起稳定系数之间的关系,结果表明:随着开挖深度的增加,地表最大沉降呈现减少的趋势;支撑系统刚度对地表最大沉降的影响较大,基坑周围地表沉降随着围护结构最大侧移的增加而增大.相关关系明显.

Statistical analysis of the surface settlement regulation around deep excavations

The relationship between the largest surface settlement around deep excavation and the location of the largest surface settlement with the depth of excavation,the insertion ratio of retaining structure and the stiffness of support system and the stability factor of resist upheaval are analyzed.The results show that the largest surface settlement around the pit shows downward trend with the depth of excavation increasing,the stiffness of support system have a great impact on the largest settlement of the deep excavation,with the maximum lateral displacement of retaining structure increasing,the largest surface settlement around the excavation will increase as a linear growth.
