摘要
通过建立3x3群桩理论模型,对单桩沉降、桩体间的相互作用、群桩沉降和内力进行理论分析计算,研究桩径、桩长、桩间距及桩基不同位置对群桩基础承载特性的影响规律,提出软弱地层中超长群桩基础的优化设计方法,从理论上解决了群桩基础中各桩受力不均匀的问题.
Abstract
This paper built a theoretical model of 3x3 group piles which can analyze and calculate the single-pile settlement,pile interaction,group pile settlement,and internal force,to study the influencing law of pile diameter,pile length,pile spacing,and different positions of pile foundation on the bearing characteristics of group pile foundation.The optimization design method for the extra-long group pile foundation in the soft ground was proposed,which could theoretically solve the problem of the uneven force of each pile in group piles.
