Application of Key Construction Technologies for Superstructure of High-Pier and Large-Span Rigid Frame Bridges
Due to the influence of topography and landform,the construction method of high-pier and large-span rigid frame bridge is mostly adopted in western China.However,due to the thin-walled,large-span and high-pier development directions,the structural stiffness decreases and the flexibility increases,and the cantilever construction method is needed for the superstructure to improve the engineering quality.Therefore,this paper takes the characteristics of high-pier large-span rigid frame bridge as the starting point,combines with a bridge engineering case,analyzes its topography and landform,hydrogeology and engineering characteristics,and accordingly proposes the application measures of key technologies for superstructure construction,so as to provide reference for relevant workers.
