Abstract:

为研究超大跨径CFRP缆索悬索桥的静力特性,并比较其与传统钢悬索桥静力性能的区别,探索性设计了主跨分别为2000m、3000m的CFRP缆索悬索桥和钢缆索悬索桥,以及主跨为5000m的CFRP缆索悬索桥,采用有限元法对比分析了这几种悬索桥在恒载、汽车荷载以及温度作用下的内力和变形。结果表明在恒载作用下,随着跨径的增大,结构内力迅速增大,且跨径越大增长速度越快,相同跨径条件下,CFRP缆索悬索桥主缆张力、吊索平均索力均小于钢缆索悬索桥的相应值,但加劲梁最大弯矩值略大;在汽车荷载作用下,CFRP缆索悬索桥的竖向位移稍大于钢缆索悬索桥的相应值;在温度作用下,CFRP缆索的内力增量和竖向位移较钢缆索的相应值小很多。
