简介:摘要:径河五路跨径河桥工程位于武汉市东西湖区,北接径河五路与滨河北路交叉口,南接黄狮海东路与滨河南路交叉口,全长349.922m,其中桥梁部分长约287.300m,路基部分长62.622m,路线平面为直线,与径河正交。其中径河五路及其与滨河北路交叉口已进入施工阶段,黄狮海东路及其与滨河南路交叉口和本项目同期设计。桥梁跨径布置为2×(4×35)m等宽宽桥。大悬臂展翅连续箱梁,设计为大展翅造型连续梁桥,桥梁两侧采用规律的隔板和椭圆形镂空处理,结合桥下V型墩身,犹如大鹏展翅,力感十足。全桥线形流畅,体现了桥梁作为交通通道的速度感与力量感,大展结构的律感强烈,桥下视野通透,墩、梁造型和谐统一。桥型设计体现了简洁、明快、不张扬的设计理念,与周围环境融为一体,还水面一种静悄悄的状态。
