摘要
肯尼亚内马铁路一期跨越B3公路特大桥工程具有道路运输繁忙,对施工安全要求高,施工安全风险大的工程施工难点。针对此工程,设计采用(40+64+40)m槽型梁跨越,并通过有限元软件midas对结构设计进行数值仿真建模,采用设计荷载和组合分析了槽型梁结构的安全性,对槽型连续梁支架施工关键技术进行了详细介绍。
The first phase of Kenya-Malaysia Railway Bridge Crossing B3 Highway has many difficulties,such as busy road transportation,high requirements for construction safety and high construction safety risks.In this paper,the channel beam span of(40+64+40 m)m is adopted in the design of this project,and the numerical simulation modeling of the structure design is carried out by the finite element software midas.The safety of the trough beam structure is analyzed by using the design load and combination,and the key construction technology of the groove continuous beam support is introduced in detail,which not only ensures the safety of the project,speeds up the construction period,but also plays a good exemplary role.It has important reference significance for similar projects in the future.
