[0038] Example 1
[0039] An arch bridge reinforcement structure without interruption of traffic according to the present invention, such as figure 1As shown, it includes a steel frame arch 1 with hinge supports at both ends, and the hinge supports are provided on the corresponding retaining walls 3 through vertical supports, and the retaining walls 3 are located at the corresponding existing bridge abutments 4. At the front wall, the hinge support abuts against the corresponding front wall of the existing bridge abutment 4 through the lateral support 9, and the steel frame arch 1 can be Abut the existing arch ring 2 .
[0040] Specifically, the steel frame arch 1 is a two-hinged arch structure, and its structural rigidity is greater than that of a three-hinged arch, and the arch foot only transmits force but not bending moment, which has lower requirements on the foundation and is more conducive to temporary reinforcement construction. .
[0041] The structural parameters ...
