General construction method for partially ground-anchored cable-stayed suspension bridge
The invention discloses a general construction method for a partially ground-anchored cable-stayed suspension bridge, which belongs to the technical field of bridge construction. According to general construction method for the partially ground-anchored cable-stayed suspension bridge, a cable-stayed area girder section and a suspension area girder section of the cable-stayed suspension bridge are simultaneously erected and constructed; before the construction of the cable-stayed suspension bridge, a reasonable completed bridge state of the cable-stayed suspension bridge is determined by using a reasonable completed bridge state determining method which takes stiffness distribution into consideration; and during the construction of the cable-stayed suspension bridge, the closing of a cable-stayed area girder section girder and a suspension area girder section girder is finished by using a closing method for the cable-stayed suspension bridge. As the cable-stayed suspension bridge is erected by using the general construction method disclosed by the invention, the girder erecting speed can be effectively increased, a problem that solidified parts formed after a pylon and girder temporarily solidifies bears a greater horizontal force can be avoided, the construction period is greatly reduced and the construction strength is reduced.
