摘要
上海申江南路（沪南公路～奉贤区界）道路新建工程在跨越大治河处需新建桥梁，大治河为Ⅲ级航道，河口宽102m，要求桥梁结构一跨过河，为满足桥位处航道通航要求、地下管线避让要求及道路设计总体要求，对桥位处新建桥梁对交叉口道路的影响、新建桥梁与河道驳岸关系的处理等方面进行研究，经多方面比选选择了单跨116m跨径的下承式系杆拱桥作为跨河主桥结构。
A new bridge is required to build across Dazhi River in Shanghai South Shenjiang Road(Hunan Highway ~ Fengxian District boundary) Construction Project. Dazhi River is the Class III channel river and its river mouth is 102 m wide. The bridge structure is required to cross river by one span. In order to satisfy the shipping requirement of channel at the bridge position, the avoidance requirements of undergroundpipelines and the master requirement of road design, the article studies the influence of newly built bridge on the crossing road, and the relationship of the newly built bridge and the river revetment. According to the selection and comparison, the 116-m single-span through bowstring arch bridge is selected as the main structure of the bridge across the river.
