Abstract

In the bridge design across the river, the cable-stayed bridge has become a very competitive bridge type. As the bridge instability occurred, the cable-stayed bridge instability problem is also of concern. In recent years, in order to meet the needs of production and life, multi-tower cable-stayed bridge has also emerged. In the multi-tower cable-stayed bridge due to the increase in the tower, the tower is not easy to control the displacement, making the already flexible structure of the cable-stayed bridge becomes softer. The possibility of instability is increased, so it is necessary to study the stability of multi-tower cable-stayed bridge. The first part introduces the research history of bridge stability analysis at home and abroad, and points out that many bridges are damaged due to instability, and the necessity of stability analysis is expounded. Then we introduce the nonlinear factors that affect the stability of the cable - stayed bridge, which introduces the causes of these factors, the mathematical calculation methods, and how to eliminate these unfavorable factors. Finally, the method of stability analysis of cable - stayed bridge is put forward, which is divided into simplified method and accurate calculation method.
