4、 upper stream of Minhang and Fengxian,and 1.7km from Fengpu Bridge down,Minpu Bridge II is a super large bridge with integrated double decks for highway and railway traffic.The main part is formed by a double-deck cable-stayed bridge with a single pylon and double cable sectors,and the main span is

5、251m wide.The upper deck is 18m in width,used for a two-way four lane highway(Class II);the lower deck is for two light rails,i.e.Shanghai Rail Transit Line 5 in Min-Feng Section,with the minimum functional width of 10m.外文翻译原文-2-Figure 1 The layer of the main bridge2.COMPARISON OF OPTIONS FOR MAIN G

6、IRDERWith only a few exceptions,the large span double-deck bridges built usually use the steel truss girder for the main girder,which is no doubt more appropriate in terms of structural performance and construction applicability.The effect of the trussed girder is different,subject to the arrangement of members,so it is critical to select an optimal design adaptable to the type of bridge.In the design of the main trussed girder on the main span of Minpu BridgeII,comparisons and studies are carri
