深基坑混凝土支撑位置对灌注桩变形的影响研究

Research on the influence of concrete support position on the deformation of cast-in-place piles in deep foundation pit

针对城市中高层住宅深基坑开挖过程中的灌注桩基础变形的问题,通过研究不同的混凝土支撑位置对灌注桩变形的影响,结合现场实测数据,对不同混凝土支撑位置对基坑支护可靠性进行评价,从而对深基坑的支护形式提出合理建议。

In order to solve the problem of deformation of cast-in-place pile foundation during the excavation process of deep foundation pits for high-rise residential buildings in cities,this article studies the influence of different concrete support positions on the deformation of cast-in-place piles.According to the on-site measured data,the reliability of foundation pit support is evaluated for different concrete support positions,and reasonable suggestions are proposed for the support form of deep foundation pits.
