南浦大桥 旁注
在上海的黄浦江上,耸立起一座全长8346米的崭新的桥梁——南浦大桥。这是一座集众多全国之‘最’于一身的桥梁。
“南浦大桥是一座双塔双索面斜拉桥,主桥长846米,以一跨423米过江,跨度之大为全国之最。
“主桥桥面用钢材与混凝土两种建筑材料叠合而成。桥面下一层用大型‘工字钢’制成框架,上一层是钢筋混 凝土桥面板,钢框架与桥面板用电焊焊接,结合处再浇上混凝土,使两者联成一体。这种叠合组成的桥面和钢框架共同受力的新型结构,叫叠合梁结构。这在我国还是第一次采用,开了我国建桥史上的先河。
“主桥桥面的钢框架共有438根钢梁,其中一根重80吨,为全国之最;制作钢梁用的钢板,最厚的达80毫米,其厚度在钢结构中又是一个全国之最。拼装钢框架用的10多万套高强度螺栓的直径达30毫米,螺栓之大,是我国建桥史上前所未有的。
“大桥主桥桥面是用180根钢索‘吊’在桥塔上的。其中最粗的一根钢索是用265根直径7毫米的高强度钢丝绞合而成,直径146毫米,重21吨,均为全国第一。它长达223米,竖起来相当于三幢国际饭店的高度。180根钢索都是用千斤顶拉后固定在主塔上的,每个千斤顶的拉力达600吨,也是全国之最。
“南浦大桥的通航净空高度为46米,在我国桥梁中首屈一指。 “由于桥高,建桥时的作业面就更高,负责主桥桥面施工的上海市基础工程公司的干部、工人要在50米以上的高空作业,安装斜拉索则要上到110米以上才能操作。这些恐怕也算是‘全国之最’了。
“南浦大桥凝聚着广大科技工作者和施工人员的心血。它的建设对于加强浦江两岸的联系,实现党中央开发浦东的决策,有着重要的意义。”

Nanpu Bridge construction
The huangpu river in Shanghai, stand up a total length of 8346 m of the new bridge-Nanpu Bridge. This is a set of many national "most" in one of the bridge.
"Nanpu Bridge is a twin towers cable-stayed bridge, the bridge, is 846 metres long, with 423 m in a river, the span of the most greatly.
"The main bridge deck with rolled steel and concrete composite and two kind of building materials into the next layer. Bridge deck with large range made framework," "a layer is reinforced coagulation TuQiao panel, steel frame and bridge panel with electric welding welding, attaches to pour concrete, make the two as one. This composite composed of bridge deck and steel frame of the new structure, common force called composite beam structure. This in our country is the first use, and opened the our country on the bridge-building precedent.
"The bridge, the bridge, the steel frame 438 root steel beam, one of the root weight of 80 tons, the most; making for the steel plate, with most of the 80 mm thick, the thickness of the steel structure is a national of the most assembled with steel frame. More than sets of high strength bolts of up to 30 mm in diameter, bolts, is our country bridge-building unprecedented.
"The main bridge deck is to use 180 a cable crane 'on' bridge tower. One of the most thick a a cable with 265 root is 7 mm diameter of high strength steel wire twisted together, 146 mm diameter, heavy 21 tons, are all the whole nation the first. It is 223 meters long, up to three house is equivalent to the height of the international hotel. 180 a cable with a jack is back in the main tower of the fixed on, every jack pulling force of 600 tons, was also the most.
"The Nanpu Bridge navigation headroom for 46 m, in our country is second to none." because of the bridge, construct the high bridge when the coolie bridge deck is higher, responsible for the construction of Shanghai foundation engineering company's cadres and workers in the 50 m to more aerial work, installation is to stay cabls up to 110 meters above to operate. These I'm afraid is the "national".
"Nanpu Bridge condensing large science and technology workers and construction personnel of blood. It to enhance the construction of the huangpu river of contact, realize the central party committee of pudong development decision-making, has the important meaning."
