摘要
在区域性互通立交跨线桥的设计过程中,基于节约用地、减少扰民、提高工程安全性等原因,对上海浦东区杨高路立交桥原设计钢箱梁横截面进行优化,提出非机动车道和调整跨线桥主线桥梁两种方案并进行分析对比,结果表明两种优化方案均在之前基础上有明显改善。
During design of local interchange flyover of Yanggao Road in Pudong district of Shanghai,the cross section of steel box beam in the original design scheme is optimized to save land,reduce noise and improve engineering safety.Two schemes,including changing non-motorized vehicle lane and adjusting artery bridge of the flyover,are analyzed and compared with each other.The analysis result shows that both of these optimization schemes could obviously improve the original design.
