钢混组合梁宽桥的箱室划分研究

tudy of Division of Box Chamber for Steel-concrete Composite Beam Wide-deck Bridge

为研究钢混组合宽桥的最优箱室划分方法,分别从桥梁纵向受力、桥面板横向受力以及相关工程措施等角度,采用控制变量法,依照现行桥梁设计规范,对组合梁案例进行了计算和分析,得出了较为经济、合理的组合梁宽桥箱室划分方法和建议参数值。

In order to study the optimal division method of the box chamber for steel-concrete composite wide-deck bridge,respectively from the perspective of longitudinal stress of the bridge,transverse stress of bridge deck and related engineering measures,the control variable method is used to calculate and analyze the case of composite beam according to according to the current bridge design specifications.The economical and reasonable method of dividing the box chamber of the composite beam wide-deck bridge is given,and the suggested parameter values are obtained.
