连续刚构特大桥0号块扭转应力设计计算探讨

摘要

With one curved high-pier continuous rigid frame super-large bridge in southwest region as an example of calculation, this paper introduces design information of the bridge, and based on spatial definite element analysis introduces combinations of torsional stress of No. 0 block, the maximum torque momont value of structure under various working conditions and stress nephogram of No. 0 block under the worst working condition to provide reliable bases for structural design and construction arrangement of No. 0 block, and draws a conclusion that design of torsional stress of No. 0 block of continuous rigid frame super-large bridge satisfies the requirements of the relevant specifications.%以西南地区一座曲线高墩连续刚构特大桥为计算实例，介绍该桥的设计信息，并基于空间有限元分析，介绍该桥0号块产生扭转应力组合情况、各工况下结构最大扭矩值及最不利工况下0号块应力云图，为合理确定0号块的结构设计和构造布置提供可靠依据，并得出连续刚构特大桥0号块扭转应力设计满足相关规范要求的结论。
