摘　　要：桩基础作为建筑结构与地基之间连接的重要结构,主要起到支撑上部结构的作用,广泛应用于桥梁等建筑结构中。本文结合现场桥梁桩基础的单桩静载试验数据,进行桥梁单桩竖向承载力特性分析,结合桩长、桩径等分析桥梁桩基础的竖向承载力特性,总结出桩基竖向承载力特性影响因素及影响规律,基于此规律提出优化桥梁桩基础的设计方案,提高桩基础的使用效率。Pile foundation,as an important structure connecting building structure and foundation,mainly plays the role of supporting superstructure and is widely used in bridges and other building structures.Based on the static load test data of single pile of bridge pile foundation on site,it is analyzed the vertical bearing capacity characteristics of single pile of bridge and the vertical bearing capacity characteristics of bridge pile foundation with pile length and diameter to summarize the influencing factors and influencing rules of the vertical bearing capacity characteristics of pile foundation,and propose the design scheme to optimize the bridge pile foundation and improve the use efficiency of pile foundation based on this rule.
