Taking a composite beam cable-stayed bridge as the engineering background,uses the finite element numerical method to performe the linear elastic stability analysis.The bare tower state,the tension-half cable state and the operation state of the completed bridge was studied.Analyzed the impact of construction line errors on the stability of bridge opera-tion status.The results show that the stability of the bridge meets the requirements of the code,and the tower construction error has little influence on the safety factor of the linear elastic stability of the completed bridge.
