连续基坑开挖对相邻基坑的变形影响分析

Analysis of the effect on deformation of adjacent pits in continuous pits excavation

在厂房内经常会出现一排或几排深基坑群的开挖施工,这些基坑周边通常存在临近的建筑物或已建的基坑群,而在深基坑工程的设计中,基坑开挖引起的附加变形必须满足周边建(构)筑物提出的严格要求.通过基坑工程的实测数据,对基坑开挖引起的周边环境及群坑之间的相互影响进行分析,为类似基坑工程的设计和施工提供有益参考.

A row or several rows of continuous deep foundation pits are often excavated in industrial buildings.Nearby structure and built pits exist around the excavated pits usually,and the strict requirement that the additional deformation caused by excavation should meet the adjacent buildings（structures） considered in the design of deep foundation project.The actual excavation monitoring data,the effects on surrounding environment and the interaction of pits in excavation are analyzed in this paper.It offers beneficial reference for similar design and construction of deep foundation projects.
