大直径扩底抗拔桩在于家堡工程中的应用

On application of large-diameter anti-uplift pile with enlarged bottom in project of Yujiabao

通过分析现有的抗拔桩承载力计算方法,结合于家堡工程地质概况对抗拔桩进行了设计,并对桩基础进行了预埋荷载箱自平衡静载试验,以配合桩基设计,满足施工要求。

According to the analysis of the current calculating methods for the loading performance of anti-uplift pile, the paper designs the antiuplift pile by combining the geological survey of Yujiabao project, undertakes the pre-buried load cell serf-balanced static experiment on the pile foundation to match the design for the pile foundation, and to meet the construction demands.
