中小跨径桥梁截面优化设计研究

Research on the Optimal Design of the Cross section of Mediumand Small-Span Bridges

公路工程建设的高速发展,实现了对道路桥梁工程发展的有效推动,各种类型的桥梁,尤其是中小跨径桥梁数量和规模均在显著增加。为确保能够更好地完成桥梁结构设计,设计人员一直在对桥梁设计尤其是截面设计进行优化,希望能够通过合理进行截面设置的方式,保证桥梁整体结构的设置质量,确保桥梁项目后续能够得到高质量使用,为地区交通发展做出更大的贡献。该文将以滨河路项目为例,通过对项目基本情况的介绍,对遗传算法和结构优化相关内容进行分析,并以此为切入点对中小跨径桥梁截面优化设计展开深度探讨,旨在提高中小跨径桥梁截面优化设计水平,推动我国桥梁工程稳定性发展。

The rapid development of highway engineering construction has effectively promoted the development of road and bridge engineering,and the number and scale of various types of bridges,especially medium-and smallspan bridges,are significantly increasing.In order to ensure that the bridge structure design can be better completed,designers have been optimizing the bridge design content,especially the section design,and hoping to ensure the design quality of the overall structure of the bridge through the reasonable setting of the section and ensure that the bridge project can be used with high quality in the future,so as to make greater contributions to the development of regional transportation.This article will take the riverside road project as an example,analyze the relevant content of the genetic algorithm and structural optimization through the introduction of the basic situation of the project,and use this as a starting point to conduct in-depth discussions on the optimal design of the cross section of mediumand small-span bridges,aiming to improve the optimal design level of the cross section of medium-and small-span bridges and promote the stable development of bridge engineering in China.
