摘要
以武广客运专线上双块式无砟轨道路桥过渡段处的端梁为例,运用被动土压力法和有限单元法,计算端梁的弯矩并对其配筋和尺寸优化证实,武广客运专线端梁尺寸合理,受力钢筋可适当减少。
Taking the end girder in road-bridge transitional section of double-slab ballastless track in Wuhan- Guangzhou passenger dedicated line for example, this paper calculates the bending moment of end girder and optimizes its reinforcing bars and dimension with passive earth pressure method and finite element method, and approves that end girders in Wuhan-Guangzhou passenger dedicated line are rational in dimension but the stressed reinforcing steel bars can be reduce properly.
