【摘要】 以浙江义乌宾王大桥为工作背景,对外界温度特别是非线性温度作用于钢管混凝土拱结构所受内力、应力作一番研究与探讨,同时对钢管拱结构的设计温度影响因素进行分析,得出影响规律。研究成果可为进行钢管混凝土拱桥结构温度应力计算的合理设计提供理论基础。更多还原

【Abstract】 With the background of Bingwang Bridge in Yiwu,Zhejiang,the internal force and stress were researched,which were of the steel tube concrete arch structure influenced by external temperature especially the nonlinear temperature.The influence rule was obtained by making analysis on design temperature impact factor of steel tube arch structure.The research results could provide theoretic basis for rational design of the structure temperature stress calculation of the concrete-filled steel tube arch bridge.更多还原
