上海软土地区预应力桩单桩水平承载力研究

Lateral capacity of prestressed piles in Shanghai soft soil

摘要: 结合上海软土地区预应力桩单桩水平静载荷现场试验,探讨预应力桩单桩水平承载力的试验判定标准,根据现场试验结合数值分析方法,对实际工程中常采用的混凝土灌芯和桩型选取（AB型、B型等）对预应力桩水平荷载性状的影响进行了分析研究,为软土地区预应力桩的设计提出了一些参考建议。

Abstract: Combined with the horizontal static load tests in Shanghai, the standard of horizontal static load tests is studied. Through the static load tests and FEM, the horizontal bearing capacity of different types of prestressed piles and the influence of core grouting on their horizontal bearing capacity are discussed. Based on this research, some suggestions are given to pile design in soft soil.
