摘要
荆州长江公路大桥北汊通航孔桥为主跨 5 0 0m双塔双索面预应力混凝土斜拉桥 ,其主梁为肋板形式 ,结构的非线性影响使结构分析较复杂。借助 1∶30的整体模型 ,研究了施工阶段、成桥阶段全桥主梁的应力水平及分布状况。
Jingzhou Changjiang River Highway Bridge is a double cable plane double pylons prestressed concrete cable stayed bridge with the main span of 500 m. The main girder is rid plate girder. The structure analysis is complicated for its structure nonlinear influence. The stress level and distribution of the main girder during construction and service stage at 1/30 model are studied.
