摘要
本文借助于MIDAS/Civil 6．70软件,运用梁格法对吉林雾凇立交工程中的钢筋混凝土连续异形箱梁建立空间模型,主要探讨了在恒载、活载和温度荷载作用下三种不同的支座布置形式对支座反力和纵梁内力以及变形的影响,并选出最优方案,为类似的工程设计提供参考。
With the aid of MIDAS/Civil 6.70 software, spacial model of Wusong grade separation project of reinforced concrete irregular box girder in Jilin was developed by using the gridiron method. This article discussed the influence of three different support arrangements on the support forces, the internal forces and deformation of longitudinal girders under dead load, live load and temperature load. The best solution was selected based on the study, which provides references for the design of the similar projects.
