摘　　要：针对某地铁线高架桥斜向跨越地面公路,需设计门式结构作为高架桥支撑体系的情况,选用钢结构门架作为该处高架桥梁的支撑体系,并对此处钢门架的尺寸进行了初步拟定、详细计算分析优化,最终确定了钢门架的尺寸及细部构造形式。Contrapose a subway line viaduct diagonally across the ground highway, a portal frame should be designed as support system for the vi- aduct, select the steel portal frame as support system for the viaduct. The size of the steel door frame were preliminary and detailed calculation a- nalysis and optimization, and ultimately determine the size and structure in the form of detailed steel door frame.
