桩偏位后两桩承台内力协同分析与配筋设计

两桩承台桩位偏差超限时,基于桩与承台共同工作的特性,提出了桩、承台与地基受力协同分析的方法,并对一工程实例提出了处理方案。对于承台,一般应进行扭矩-地基反力协同分析,并通过配筋设计满足承载力要求。当通过协同分析能够满足承载力要求时,可不必对偏位桩进行过度处理,以节省施工费用,加快施工进度。

Synergy analysis of the cap with two piles which piles deviation overrun and the reinforcement design

Two piles cap which piles deviation overrun,based on the characteristics of the cap work together with the piles,raised an analysis method which collaborative the piles,cap and the foundation,and the treatment scheme is proposed with a project. For the piles cap,in general should be synergy analysis the torque-ground reaction force,and through the reinforcement design to meet the capacity requirements. When the synergy analysis can meet the requirements,should not be excessive treatment on the deviation piles,in order to save the cost,speed up the construction progress.
