Rigid frame bridge reinforcement method employing short tower-deck type suspension bridge structure system
The invention discloses a rigid frame bridge reinforcement method employing a short tower-deck type suspension bridge structure system. The stress system of a rigid frame bridge is changed through introducing the short tower-deck type suspension bridge structure system, the stress system of the original rigid frame bridge is subjected to the unloading effect and thus long-term down warping due to shrinkage and creep of concrete of the rigid frame bridge is restrained. By applying the rigid frame bridge reinforcement method, the problem of long-term down warping of the rigid frame bridge is greatly improved, the bearing capacity and structure durability of the rigid frame bridge are improved, and the rigid frame bridge reinforcement method has very high engineering promotion values.
