快速路高架桥跨湖段综合设计——以武汉市墨水湖北路西段跨龙阳湖段设计为例

Integrated Design of Cross-lake Expressway Viaduct:Taking the Design of The West Section of North Moshuihu Rd. Crossing the Longyang Lake in Wuhan for Example

快速路高架的跨湖桥与一般道路的跨湖桥,两者的建设出发点不同,设计的侧重点及考虑因素亦各有偏重。以武汉市墨水湖北路西段高架桥跨龙阳湖段设计为例,从道路交通、桥面雨水汇集、桥梁景观、施工方案等4个方面进行综合分析,分别从各专业设计的角度以"跨湖段高架桥"为出发点,在设计过程中统筹考虑高架桥的使用功能和景观效果这两大因素,整理设计思路,提醒注意事项并介绍相关设计技巧,以供广大同行参考和借鉴。

The cross-lake expressway viaduct is different from the general road cross-lake one in the purpose of construction and the emphasis and considerations of design. Taking the design of the west section of North Moshuihu Rd. crossing the Longyang Lake in Wuhan for example and analyzing the case comprehensively from four aspects including road traffic, deck rainwater collection, bridge landscape and construction schedule. Based on the starting point of the crosslake viaduct from every specialty design, the design takes into account both its functional and visual effects during the whole process. Furthermore, the design concepts, cautions and relevant design techniques are summarized and introduced, which may provide references for the vast colleagues.
