桩基素混凝土段合理长度的设置

Settings for the reasonable length of plain concrete section of pile foundation

目前,公路桥梁设计规范中均无关于钻孔灌注桩素混凝土段的规定,仅建筑地基基础设计规范有规定。文章根据内蒙古桥梁建设,结合理论分析陈述了素混凝土段受力原理及设置,希望对相关技术人员有参考作用。

At present, the highway and bridge design specifications have no provisions on plain concrete section of bored piles, only the building foundation design specification with norms. According to the bridge construction in Inner Mongolia, com- bining theoretical analysis presented plain concrete stress principle and setting, hope to provide reference for relevant technical staff.
