摘　　要：连续刚构桥由于墩梁固结,省去了支座,在施工中可利用悬臂浇筑法施工,不影响桥下交通,并且集连续梁和刚构桥的优点于一身,整体性及行车舒适性好,所以该桥型获得了较为广泛的应用.有限元法计算理论及计算机技术的发展使桥梁仿真分析计算取得了较大发展,桥梁仿真分析计算使得桥梁计算简便快捷.以某连续刚构桥为例,进行了该桥自重及温度效应的二维仿真分析计算,并对自重及温度效应二维仿真分析计算结果进行了对比分析.Due to the consolidation of pier and beam,the continuous rigid frame bridge saves the support.In the construction,the cantilever pouring method can be used,which does not affect the traffic under the bridge,and integrates the advantages of continuous beam and rigid frame bridge,with good integrity and driving comfort,so this type of bridge has been widely used.With the development of finite element theory and computer technology,Great progress has been made in bridge simulation analysis.The bridge simulation analysis makes the bridge calculation simple and fast.Taking a continuous rigid frame bridge as an example,the two-dimensional simulation analysis and calculation of self weight and temperature effect of the bridge are carried out,and the two-dimensional simulation analysis and calculation results of self weight and temperature effect are compared and analyzed.
