Abstract
Provided is a mounting method of a main beam of a double-sided steel box UHPC composite beam cable-stayed bridge and a composite beam thereof. The method includes the following steps: carrying out prestressed tensioning in a transverse direction of the bridge for all beam segments; pouring UHPC when a wet joint between a second beam segment and a third beam segment located in front of an end beam segment is in a pre-bending state; initially matching and positioning the end beam segment and a beam segment to be mounted; tensioning a n-th stay cable corresponding to the end beam segment for the first time; tensioning the n-th stay cable for the second time to a designed cable force.
