桩锚式支护结构的变形特性研究

Research on the Deformation Character of Anchor Piles Retaining Structure

通过对西安某商住楼深基坑桩锚式支护结构水平位移的计算与监测,研究分析了在深基坑开挖过程中桩锚支护体系的变形特性,得出支护桩的水平位移随开挖工况而变化的分布规律,认为在基坑工程常规设计中应考虑时空效应的影响。

The horizontal deformation of the excavation support is one of the most important factors for retaining structure design.Based on field measured data and calculated result about the horizontal deformation the anchor piles retaining structure of the building's deep pit in Xi'an,the deformation character and the level deformation distribu- tion of anchor piles retaining structure for deep pit are studied in this paper.It is concluded that in pit design the time -Space effect should be considered.
