Construction method for controlling arch springing thrust in construction process of simply supported arch bridge
The invention discloses a construction method for controlling arch springing thrust in the construction process of a simply supported arch bridge. The construction method comprises the following steps: constructing piers, end cross beams and skewbacks; a balance cable system for resisting arch springing thrust generated by arch rib hoisting is installed, and the balance cable system comprises a balance cable, a bearing cable, a traction rope, a lifting rope, a stabilizing rope and a roller bracket; arch ribs are installed, the tensioning force of balance cables is adjusted in real time, and arch springing displacement is controlled; after the arch ribs are installed and closed, the balance cables are converted into temporary tie bars to control displacement of arch feet, and a balance cable system is dismantled; concrete in the pipe is pumped, a longitudinal beam is installed, the tensioning force of a temporary tie bar is adjusted in real time, and arch springing displacement is controlled; installing small longitudinal beams and part of cross beams, dismantling temporary tie bars, and constructing a bridge deck system. According to the construction method for controlling the arch springing thrust in the construction process of the simply supported arch bridge, by arranging the balance cable system, the end cross beam supporting columns and the temporary tie bars, the high efficiency of arch springing thrust control, the operation safety and the structural reliability are achieved.
本发明公开一种控制简支拱桥施工过程拱脚推力的施工方法，其包括以下步骤：桥墩、端横梁和拱座施工；安装抵抗拱肋吊装产生拱脚推力的平衡索系统，平衡索系统包括：平衡索、承重索、牵引绳、吊绳、稳定绳和滚轮托架；安装拱肋并实时调整平衡索张拉力，控制拱脚位移；拱肋安装合龙后，平衡索转换为临时系杆控制拱脚位移，拆除平衡索系统；泵送管内混凝土和安装纵梁，实时调整临时系杆张拉力，控制拱脚位移；安装小纵梁和部分横梁，拆除临时系杆，桥面系施工。本控制简支拱桥施工过程拱脚推力的施工方法，通过设置平衡索系统、端横梁支撑柱和临时系杆，实现拱脚推力控制的高效性、操作的安全性和结构的可靠性。
