摘要
文中对基坑开挖过程中各施工步骤下邻近建筑物的监测数据进行分析.结果表明,邻近建筑物的水平及竖向位移均随着基坑开挖深度的增大而增加,且开挖工况的变形远大于支护工况;支护结构顶部的水平位移随着基坑开挖深度的增大而增加,支护结构位移远大于邻近建筑物位移,支护措施有效限制了坑顶位移;各施工步骤下,深层水平位移随着开挖深度的增加呈现先增大后减小的"鼓肚状".
Abstract
Analyze the monitoring data of adjacent buildings at each construction step during the excavation process of the foundation pit.The horizontal and vertical displacement of adjacent buildings increase with the depth of excavation of the foundation pit,and the deformation of the excavation condition is much greater than that of the support condition.The horizontal displacement of the top of the support structure increases with the depth of excavation of the foundation pit,and the displacement of the support structure is much greater than that of adjacent buildings.The support measures effectively limit the displacement of the top of the pit.The deep horizontal displacement under each construction step shows a"bulge shaped"pattern of first increasing and then decreasing with the increase of excavation depth.
