Abstract :
To ensure passenger comfort and safety of train operation, high-speed rail on track for Comfort demanding, and concrete shrinkage and creep is the impact on passenger line prestressed concrete continuous bridge of track an important factor, so construction control post creep of concrete proposals to decrease the method is very necessary. The article taking the high-speed railway for engineering background, the finite element model of the bridge, analysis and without considering the effects of shrinkage and creep deflection of the bridge.In the construction process and construction process and puts forward some solutions design aspects of creep deformation. For the future of the railway bridge creep deflection control provides some technical method.
