摘要
Abstract
In order to optimally select a butterfly arch bridge that integrates functional and aesthetic values,a calculation and analysis were conducted to optimize key structural control parameters,including the outward inclination angle of the side arches,the stiffness ratio between the arch and the beam,and the rise-to-span ratio of the middle arch.This process resulted in well-coordinated and mechanically reasonable control parameters.By adopting these optimized design parameters,the bridge design demonstrates excellent stability,rational struc-tural stress,and an elegant appearance,effectively meeting the requirements of the bridge location environ-ment,structural mechanics,and aesthetic design.关键词
