摘要
在分析安徽省望东长江公路大桥所在的东流水道河道及航道条件的基础上,从通航的角度,对拟建的安徽省望东长江公路大桥通航净空尺度进行计算,对通航桥孔布置进行分析,并结合桥区航道条件,针对原桥型方案存在的问题,对桥墩布置方案进行优化分析,优化后的桥型方案(通航孔布置为78 m+228 m+638 m+228 m+78 m)能较充分地利用有效通航水域,适应航道条件变化较强,该桥型方案合理可行。
Based on the analysis of Anhui Wangdong Yangtze River bridge in the Dongliu and the basis ot me conditions of the river channel, from the point of view of the navigation, this paper proposes the navigation clearance dimensions calculation of Anhui Wangdong Yangtze River bridge, analyzes the navigation layout. Combining with the channel condition, the arrangement for the bridge pier optimizationd is analyzed. According to the bridge area waterway＇s condition, and in view of the existing problems of bridge type scheme, this paper analyzes the pier layout＇s optimization. The optimized bridge type scheme （78 m＋228 m＋638 m＋228 m＋78 m ） can make full use of the effective navigable water, and adapt well to the channel condition, thus the bridge type scheme recommended is reasonable and feasible.
