某匝道桥撞损桩基的加固设计及处理措施

The Strengthening Design of a Ramp Bridge Collision Damage of Pile Foundation and Treatment Measure

本文以工程实例，验证了人工静压 PHC 管桩加固撞损桥梁桩基，其入土长度和竖向承载力均可达到设计要求和使用要求，桥梁横向抗推刚度也得到了提高，为同类桩基加固处理提供了参考。

Based on the engineering example, this article ve-rifies the col ision damage of pile foundation with artificial static PHC pipe pile strengthening bridge, both of the embe-dded length and vertical bearing capacity can meet the design requirements and usage requirements, lateral rigidity of bridge is also improved, and provides reference for similar pile fo-undation reinforcement.
