考虑土体侧向作用的高承台桥台分析研究

Analysis of pile foundations of high table abutment considering earth pressure

考虑台后土压力对高承台桥台进行了受力分析计算,考虑了承载能力极限状态组合、正常使用极限状态组合及考虑地震力的偶然组合。对桥台肋板及桩基的最不利截面进行了验算,对桩基构造尺寸进行了优化,确定了设计参数的合理性,为该类桥台桩基计算提供了借鉴。

Pile foundations of high table abutment is calculated under the earth pressure considering the uhimate limit state combination the nor- mal limit state combination and the accidental combination of seismic forces. The most unfavorable section of the bridge abutment and pile founda- tion are calculated to optimize the size of pile and determine the reasonableness of the design parameters. The results provide a reference for the class abutment pile calculated.
