Then base on theweak interference of cable displacement and near influence of hanger tension theories, deducing thesimplified computation method in construction stage. Accouding to the result from optimization, contractwith the result that from using the finite element sofeware ANSYS, we consider the geometric nonlinearand so on. Through the example proving, deduce the simplified optimization method which iseffectiveness, and disproof the weak interference of cable displacement and near influence of hangertension theories is illogicality.
