哈齐客运专线四线铁路桥墩设计

以哈尔滨至齐齐哈尔客运专线松花江特大桥主桥桥墩为例,详细论述四线铁路桥墩的设计思路与设计方法,给出四线铁路桥墩设计时应重点关注的荷载组合工况;通过对冰压力荷载的分析,提出高纬度严寒地区桥墩的设计建议,对相同类型的工程具有一定的参考和借鉴意义。

Design of Four-Track Railway Bridge Pier on Harbin-Qiqihar Passenger Dedicated Line

In this paper,the bridge pier design of the main bridge for the Songhua River super major bridge on Harbin-Qiqihar passenger dedicated line was taken as the example. Then this paper analyzed the design idea and design method for four-track railway bridge pier,and proposed the work conditions of load combination which should be focused on during design of four-track railway bridge pier. Furthermore,via analysis on ice pressure load,some advices were given in this paper regarding bridge pier design in high latitude and severe cold area,having certain reference value to the similar projects.
