In order to explore the mechanical deformation mechanism and construction control results of the special-shaped main tower of long-span single-cable plane suspension bridge,this study takes Nanning Yinghua bridge as the research background,and adopts the method of numerical calculation and field monitoring to study the main tower of the special-shaped suspension construction.The results show that the stability and force of the bridge can meet the requirements of the relevant specifications under the condition of 20℃design reference temperature.After field measurement:the main tower construction process,linear shape is good,closing accuracy meets the spec-ification requirements.
