摘　　要：红岩村嘉陵江大桥是一座主跨375m的公轨两用桥,连接重庆市渝中区和江北区。综合考虑地形限制、通航要求、技术条件、经济性能、景观风貌等因素,采用高低塔双索面钢桁梁斜拉桥方案。通过对大桥周边环境和区域文化的调研,确定了大桥景观设计以"红岩华门"为主题。在该桥景观设计中,应用竖向线条元素对门形桥塔和桥墩进行造型,形成了端严庄重的形象风格;桥塔选用赭红色可使其更醒目、突出文化立意,主梁和斜拉索选用浅灰色,与周边环境和谐相容;人行道栏杆为栅栏式FRP栏杆,造型与桥塔整体风格匹配呼应,并作为展示红岩文化的载体;景观照明灯光色彩为暖色调,采用泛光照明来表现桥塔外轮廓,钢桁梁采用内光外透表现形式,通过照明亮度分级以突出大桥夜景明暗对比关系。The Jialingjiang River Bridge in Hongyan Village,linking the Yuzhong District and Jiangbei District in Chongqing,is a rail-cum-road bridge with a main span of 375 m.The scheme of a steel truss girder cable-stayed bridge with double cable planes and with two pylons of different heights was finally chosen,based on the comprehensive analysis of an array of factors,including topographical restrictions,navigational requirements,technical level,economic performance and landscape effect.By the investigation into the surrounding environment of the bridge site and local culture,it was determined to choose the image of"Hongyan Chinese Gate"as the theme of landscape design for the bridge.In the landscape design of the bridge,the portal pylons and piers were shaped by vertical lines,emphasizing a sense of grandeur and solemnity.For the selection of colors of the components,the pylons are painted to be auburn to make them more striking and highlight its cultural implication.The main girder and stay cables are painted to be light grey to match with the surroundings.The balustrades along the footways,serving as the carriers of the Hongyan culture,are FRP railings,with shapes harmoniously echoing to the integral style of the pylons.The landscape illumination features the warm lighting effect.Floodlights outline the silhouette of the pylons against the sky and light inside the steel truss girder spills out,making the girder a visible spatial frame in the darkness.And contrast of brightness and darkness of the illumination in the bridge is realized by luminance grading control.
