Analysis on Carrying Capacity and Stability of Construction Bracket for a Railway Bridge

该文通过三维有限元数值模拟,对某铁路桥梁施工支架所用杆件的承载力及稳定性进行了分析。分析结果表明支架所采用杆件在施工过程中是安全的,支架变形满足施工要求,支架杆件及支架整体在施工过程中稳定性满足要求,同时根据支架反力求得地基所需的最小承载力。分析结果对类似工程有一定借鉴作用。

According to 3D finite element numerical simulation,the article analyzes the carrying capacity and stability of components used for the construction bracket of a railway bridge. The results shows that the components used for the bracket is safe during the construction. The deformation of the bracket meets the construction requirements. The bracket components and the whole bracket are stable during the construction. The minimum carrying capacity required for the subgrade is given on the bracket reaction. The analysis result can be referred for the similar projects.
