The Structural Design of High-Pier Long-Span Continuous Rigid Frame Bridge:A Case of Sanglong Expressway
摘要
Abstract
The prestressed concrete continuous rigid frame bridge adopts a structural form of rigid connection between pier and beam with continuous beams,which has significant longitudinal bending stiffness and lateral torsional stiffness.It can meet the stress requirements of long-span bridges and has great application advantages in mountainous areas with high piers.Taking Lijiagou Bridge on Sanglong Expressway as an example,this paper establishes a structural model with finite element software to analyze the structural characteristics and stress features of high-pier long-span continuous rigid frame bridges.It systematically introduces the overall design and key structural calculation points of high-pier long-span continuous rigid frame bridges,providing a reference for the design of similar bridges.关键词
