薄壁桥台嵌岩桩基础斜桩与直桩设计方案的比较

Comparison of Design Schemes of Inclined Pile and Vertical Pile in Embedded Rock Pile of Thin Walled Abutment

摘要:

结合莫桑比克Nampula-Cuamba道路升级改造项目第二标段Monapo桥基础桩基工程，采用Prokon 2.5结构分析软件对薄壁桥台嵌岩斜桩和直桩在不同台高和不同桩长的受力和配筋情况分别进行计算分析，从而为设计中根据不同地层条件和不同台高选择合理的桩基形式提供依据。

Abstract:

According to the pile foundation engineering of 2nd section of Monapo bridge foundation project in Nampula-Cuambaroad road upgrading and regeneration in Mozambique, calculation analysis was made on the stress and reinforcement of different base heights and pile lengths of embedded rock pile of thin walled abutment with Prokon 2.5 structure analysis software, so as to provide the basis for rational selection of pile foundation type based on different formation conditions and base heights in the design.

Key words:bridge pile foundation; thin walled abutment; inclined pile; vertical pile
