摘要
在分析钢管混凝土复合材料力学性能与混凝土龄期关系的基础上 ,以主拱组合结构的弯矩余能极小为目标 ,使成桥拱轴线逼近其恒载压力线 。
This paper forms a theory of optimal scheme of casting concrete into the bearing arch based on analysis of relationship between age of concrete and behavior in mechanics of composite material of concrete filled steel tubes,which sets an aim at minimizing energy of the composite bearing arch generated by moments to make the arch axis approach the pressure line.
