Technical Field

The multi-span continuous arch bridge is characterized by that the central arch seat is stressed by multi-arch effect, and after the bridge is formed, the horizontal thrust produced by two sides of central arch seat are opposite in direction, identical in size and balanced, and the central arch seat is only stressed by vertical pressure. However, in the arch rib hoisting process, because the cable crane can only hoist one arch rib section at a time, after the single-side arch rib section is hoisted, larger unbalanced bending moment and horizontal force can be generated on the pier body of the central arch base and the buckling tower, so that the stress of the buckling tower is increased, the buckling tower is deviated, and the arch shape is influenced. In order to eliminate unbalanced force generated during single-side arch rib hoisting, the traditional technology generally adopts a large cantilever single-tower double-buckling construction method, specifically, after the single-side arch rib is hoisted and installed in place, the single-side arch rib is temporarily connected with the upper section through an inner flange bolt between the sections, then a cable hoist is used for loosening a hook to install the other-side arch rib section, and buckling and tensioning are simultaneously carried out after the installation of the arch rib sections at the two sides is completed.

The method is characterized in that the weight of the arch rib of the section transmits load to the buckling cable of the last section through the inter-section flange, the buckling cable of the last section bears the gravity component force of the two arch rib sections at the same time, the consumption of the buckling cable is increased, the increase of the buckling cable force can lead to the increase of the input buckling tower materials, the pier body and the buckling tower are relatively larger in deflection, and the risk of the arch rib installation process is relatively higher.
