Novel suspension bridge special for track
The invention discloses a novel suspension bridge special for a track, and relates to the technical field of suspension bridges, the novel suspension bridge comprises two opposite and parallel V-shaped towers, cable systems erected on the V-shaped towers, and steel box girders used for supporting a bridge floor and vehicles; the cable system comprises two oppositely-arranged main cables, and the transverse distance between the two main cables is gradually increased from the middle to the two ends to form an outward-expanding type space cable face. The steel box girder penetrates through the two V-shaped towers, and side piers are arranged at the two ends of the steel box girder to form a three-span continuous supporting structure; the rigidity of the steel box girder changes in the longitudinal direction, the side span non-suspension area is larger than the main span suspension area, and a rigidity reinforcing structure is arranged on the bottom face of the steel box girder in the side span non-suspension area. The three-span continuous supporting variable stiffness steel box girders, the external expansion type space cable surface cable systems and the V-shaped towers are adopted, the structural transverse stiffness is improved, the main cable space effect is enhanced, structural stress is more reasonable, interference with wiring on the two banks is avoided, the manufacturing cost is saved, and the bridge attractiveness is improved.
本发明公开了一种新型轨道专用悬索桥，涉及悬索桥技术领域，该装置包括两座相对且平行设置的V形塔、搭设在所述V形塔上的缆索系统和用于支承桥面和车辆的钢箱梁；所述缆索系统包括两根相对设置的主缆，且两根主缆的横向间距由中间至两端逐渐增大形成外张型空间索面；所述钢箱梁的穿过两个V形塔，两端均设有边墩，形成三跨连续支承结构；所述钢箱梁的刚度沿纵向是变化的，边跨非悬吊区大于主跨悬吊区，且边跨非悬吊区钢箱梁底面设有刚度加强构造。本申请采用三跨连续支承变刚度钢箱梁、外张型空间索面缆索系统和V形塔，不仅提高了结构横向刚度，增强了主缆空间效应，结构受力更加合理且与两岸接线无干扰，还节约了造价、提升了桥梁美观度。
