摘要
以某斜抛撑基坑工程为例,通过分析盆式开挖阶段及斜抛撑下方土体开挖阶段的围护桩水平变形及周边建筑物沉降变形的监测资料,得到了两个开挖阶段中围护桩变形及周边建筑物沉降的变化规律。结果表明,随土方开挖,围护桩变形及周边建筑物沉降均增大,围护桩变形及周边建筑物沉降主要发生在盆式开挖阶段,因此,围护桩变形及建筑物沉降控制应以盆式开挖阶段为主。
Combined with practical project of foundation pit with inclined bracing,based on the research on horizontal deformation of supporting piles and settlement deformation of adjacent buildings in two different construction stages of basin excavation and under inclined bracing excavation,the changing regularity and relationship of horizontal deformation and settlement deformation was demonstrated.The result shows that horizontal deformation and settlement deformation are both increasing in value during excavation.Horizontal deformation of supporting piles and settlement deformation of adjacent buildings are mainly happening in basin excavation.Therefore,deformation in basin excavation should be given priority.
