摘　　要：参数化设计是基于桥梁结构设计内在联系与约束关系进行三维正向设计的一种方法,该方法可有效提高结构的调整与优化效率。在方案初步设计阶段,参数化设计理念可用于桥梁结构合理性、经济性及美观性的优化,满足现阶段桥梁造型多样化发展的社会需求;在施工图设计阶段通过调整自变量参数,可灵活地进行桥梁结构细部构造调整,并与二维设计图进行自动交互,大幅提升设计效率及质量。本文基于“R+GH”参数化平台,提出桥梁结构参数化设计流程,并通过工程案例的应用进一步验证该设计思想的实用性和高效性。Parametric design is a method of three-dimensional forward design based on the internal connections and constraints of bridge structure design.This method can effectively improve the efficiency of structural adjustment and optimization.In the plan and preliminary design stage,the parametric design concept can be used to optimize the rationality,economy and aesthetics of the bridge structure to meet the social needs of the diversified development of the bridge at present time;in the construction design stage,by adjusting the independent variable parameters,It can flexibly adjust the detailed structure of the bridge and automatically interact with the two-dimensional design drawings,which greatly improves the design efficiency and quality.Based on the"R+GH"parametric platform,this paper proposes a parametric design process for bridge structures,and further verifies the practicability and efficiency of the design idea through the application of engineering cases.
