Construction method of reinforced concrete multi-span arch bridge or continuous box structure bridge
The invention discloses a construction method of a reinforced concrete multi-span arch bridge or a continuous box structure bridge. The method is implemented according to the following steps: step 1) constructing the lower part structure of the arch bridge, wherein the lower part structure comprises a foundation, a middle pier and a bridge abutment; step 2) fixing flexible cables to piers of the arch bridge, fixing ground anchors through the flexible cables, and fixing the ground anchors to a ground to balance the horizontal force borne by the pier; step 3) erecting arch supports on each span of the bridge; step 4) constructing the upper part structure of the arch bridge on the arch supports; and step 5) removing the flexible cables and the arch supports. The construction method is simple in technology, reliable in quality, low in construction cost and rapider in construction speed, and the safety risk is lowered.
