Cable-stayed and suspension cable cooperative system bridge girder closure method
The invention discloses a cable-stayed and suspension cable cooperative system bridge girder closure method, which belongs to the technical field of bridge engineering, and comprises the following steps: collecting design parameters of a bridge; designing the position of a closure opening according to the design parameters; target suspender force of suspenders on the two sides of the closure opening is calculated; after the structures, except the cable-stayed transition section and the suspension cable transition section, of the bridge are constructed, a main beam of the cable-stayed transition section and a main beam of the suspension cable transition section are hoisted to the two sides of a closure gap, and the suspender force in the cable-stayed transition section and the suspender force in the suspension cable transition section are adjusted to the target suspender force; and closure operation of the closure opening is carried out. According to the cable-stayed and suspension cable cooperative system bridge girder closure method, rapid closure construction of a bridge structure can be achieved so as to shorten the construction period, accurate adjustment of a closure opening can be achieved, unstressed closure of the bridge structure is completed, guarantee is provided for stability of a bridge body structure, and the construction cost is reduced.
本发明公开了一种斜拉悬索协作体系桥主梁合龙方法，属于桥梁工程技术领域，步骤如下：采集桥梁的设计参数；根据设计参数设计合龙口位置；分别计算合龙口两侧吊杆的目标吊杆力；在施工桥梁除斜拉过渡段和悬索过渡段以外的结构后，吊装斜拉过渡段的主梁和悬索过渡段的主梁至合龙口两侧，并分别将斜拉过渡段和悬索过渡段中的吊杆力调整到目标吊杆力；进行合龙口的合龙作业。本发明提供了一种斜拉悬索协作体系桥主梁合龙方法，不仅能够在实现桥梁结构快速合龙施工，以实现施工工期缩短，还能够实现对合龙口的准确调整，完成桥梁结构的无应力合龙，为桥体结构的稳定提供保障，降低施工成本。
