泖港大桥主跨200米,为近年来我国建成的大跨径予应力混凝土公路斜张桥之一。全桥分三孔(85米+200米+85米),全长391.8米,宽12米(2.50米+7.00米+2.50米),载重为汽15挂80。大桥结构新颍,在设计中采用了各种新技术,如正交设计优化方案的运用;应用卡尔曼滤波理论控制施工挠度和索力;采用拉索稳定张拉力计算恒载内力以消除混凝土徐变影响;研制成大吨位冷铸镦头锚等等,为国内大跨径斜张桥的设计和建设积累了有益的经验。
The main span of the bridge is 200 meters, which is one of the long-span prestressed concrete highway slanting bridges built in our country in recent years. Full bridge points three holes (85 meters +200 meters +85 meters), a total length of 391.8 meters, 12 meters wide (2.50 meters +7.00 meters +2.50 meters), the load for the steam 15 hanging 80. New structure of the bridge structure, in the design of the use of a variety of new technologies, such as orthogonal design optimization program; application of Kalman filter theory to control the construction of deflection and cable force; the use of cable tension stabilizing force to calculate the constant load internal force to eliminate concrete Xu Become a large tonnage cold heading upsetting anchor, etc., for the domestic large-span diagonal tension bridge design and construction has accumulated useful experience.
