一、工程概况2010年上海世博会场馆选址于南浦大桥—卢浦大桥之间的黄浦江两岸及后滩地区,势必带来该区域的强势开发,并诱发世博会后远期的越江交通需求。西藏南路新建越江隧道总体走向为北接浦西西藏南路,南至浦东滨州路—博文路,建设主旨之一是为世博会提供一条主要的内部越江通道。(见图1)隧道采用城市次干路I级,设计车速为40km/h。隧道最大纵坡取4.5%,内部布置单向2车道,隧道路面宽度:0.25(路缘带)+3.75+3.50+0.25(路缘带)=7.75m,两侧各有0.25m安全带(设防撞侧石)。
First, the project overview 2010 Shanghai World Expo venues located in the Nanpu Bridge - Lupu Bridge between the banks of the Huangpu River and Beaches, is bound to bring the region’s strong development, and induced after the Expo’s future traffic demand across the river. The new Xijiang River Tunnel in South Tibet will generally be north of Puxi along Tibet Road to the south of Pudong Binzhou Road - Bowen Road. One of its main constructions is to provide the Expo with a major internal river crossing. (See Fig. 1) The tunnel adopts Grade I of the urban secondary trunk road and the designed speed is 40km / h. The maximum vertical gradient of the tunnel is 4.5%. The layout of the tunnel is one-way with two lanes. The width of the tunnel pavement is 0.25 (curb belt) + 3.75 + 3.50 + 0.25 (curb belt) = 7.75m with 0.25m safety belts on both sides Collision side stone).
