摘　　要：在结构设计中,当地基承载能力不足时,往往会采用预制或灌注桩进行地基处理。对全直桩基础结构,影响桩水平承载能力的因素是多方面的,结合算例对各影响因素及其权重进行分析,并对桩顶不同连接形式的特点及适用条件作了阐述,以期对今后的全直桩基础设计起到一定的借鉴作用。For a structure, if the bearing capacity of the foundation is insufficient, precast or casting piles are generally used. For the foundation consisting of whole vertical piles, the horizontal bearing capacity of the pile is influenced by many factors. Based on the analysis of the results of an example, this paper gives a list of the influential factors and corresponding weight to the horizontal bearing capacity. Furthermore, the characteristics of different connection modes of pile tops and relevant applying circumstances are also given, hoping to serve as a reference for the design of whole vertical-pile foundation.
