摘要
黑沟特大桥是二连-河口国道主干线内蒙古自治区集宁-丰镇段高速公路上的一座预应力混凝土连续刚构桥,利用有限元方法对该桥建立仿真分析模型,模拟桥梁的施工状态,研究悬臂施工各工况,分析其结构变形及内力、应力,为桥梁施工控制提供参考.
Heigou Grand Bridge is a prestressed concrete continuous rigid frame bridge,located on Inner Mongolia Jining-Fengzhen freeway of Erhekou national turnpike road. Based on the finite element method, an imitating model is constructed, which can be used to imitate the construction condition of bridge, to study each stage of the cantilever construction and analyze its deformation, internal force and stree. Referential materials are provided for the construction of the bridge.
