连续刚构桥双薄壁墩参数优化研究

Research on Parameters Optimization of Double Thin-Wall Piers of Continuous Rigid-Frame Bridge

考虑侧向风压产生扭转及温度变化产生纵向变形的作用 ,通过对双薄壁墩连续刚构桥的受力分析 ,探讨了双薄壁墩设计的影响因素 ,以非线性规划为基础 ,应用罚函数法对双薄壁墩参数进行优化研究。

The torque caused by transverse wind pressure and longitudinal displacement caused by various temperature are considered. The design influence factors of the double thin-wall piers are discussed in accordance with analysis of the double thin-wall piers of continuous rigid-frame bridge. On the basis of the nonlinear programming, SUMT is applied to optimize the double thin-wall pier parameters.
