摘要
通过对某高速7×120 m连续—刚构桥计算分析,采用影响矩阵和最小弯曲应变能的方法,推导了此种桥型在合龙顺序、合龙顶推力的最优化方案,并为该类型桥梁设计提供一定的参考。
Through the calculation and analysis of a continuous rigid frame bridge,the paper adopted the method of influencing matrix and the minimum bending strain energy to derive from the optimization scheme of closure order and closure jacking force for this kind of bridge.
