基于超静孔压消散的预制静压桩桩侧极限摩阻力计算
Ultimate shaft resistance of jacked piles based on excess pore pressure dissipation
摘要
Abstract
As an important component of the ultimate bearing capacity of the pile,the shaft resistance depends mainly on the effective stress in the soil around the pile.In order to take the stress changing in the soil into account during the single pile ultimate capacity calculation,attention is paid to jacked piles' characteristics to analyze the stress changing in pile regime during initial stage,installation and consolidation.The cavity expansion and consolidation theory are applied to the final normal effective stress analysis around the pile,with the ultimate shaft resistance determined by the improved effective stress method developed in this paper.The method is adopted to calculate a practical example with reasonable results obtained.关键词
