| Abstract: | In the process of hoisting arch rib of concrete-filled steel tubular arch bridge with the non-support cable erection technique,eliminating tower deviation to arch rib alignment can improve accuracy,ensure the whole bridge line.Combine the process of rib-hoisting of Hu-Rong West Xiaohe grand bridge,the author deduced the formula of deviation to arch rib elevation,and introduced the control method for deviation in actual construction,and have achieved good results. |
