description The simplified method of arch bridge suspender replacement scheme based on the measured displacement correction is proposed in order to ensure the safety of the arch bridge suspender replacement process based on the pocket hanging method. Firstly, each group of replacement suspenders is separated from the pocket hanging system regardless of the constraint effect of the bridge deck on the suspenders, and the force analysis is carried out to obtain the displacement of the bridge deck under different cases; Then, the modified coefficient is obtained by using the measured displacement at the lower end of each suspender, and the modified coefficient is used to modify the displacement of the bridge deck, so that the calculation result can be applied to the case where the stiffness of the bridge deck cannot be ignored; Finally, the correctness of the method in this paper is verified by applying it to practical engineering. It can be concluded that the proposed method is simple, easy to operate and has high precision, which can be used in the removal of arch bridge suspenders through the verification results.
