跨高速铁路桥梁基础防护桩设计与施工

Design and Construction of the Foundation Pile of the High- speed Railway Bridge

武咸城际铁路在咸宁市上跨武广高速铁路,安全风险极大。论述了跨高速铁路桥梁基础承台防护桩的设计和施工,分析了防护桩设计的影响因素,确定了计算桩长。此外,从单桩承载力、桩基内力及基地应力三方面计算进行了安全性验证,确保了桥梁承台施工安全,对类似工程的基础安全防护有较好的借鉴作用。

Wuhan -Xianning intercity railway spans Wuhan -Guangzhou high - speed railway in Xianning city and has risks . This paper focuses on the design and construction of the bearing platform fender piles of the high - speed railway bridge ,anal-yses the factors affecting the fender pile design and calculates pile length .The safety is verified from the bearing capacity of single pile ,pile foundation stress and base stress ,and the bridge construction safety is ensured .It has a good reference for the basic safety protection of the similar engineering .
