| 摘 要： | 上承式梁拱组合体系桥是上承式拱桥和连续梁组合受力的一种桥梁形式,有经济性能好、承载能力大、结构轻盈等特点.通过采用预应力筋来平衡拱脚的推力,发挥了拱梁混凝土和预应力钢筋各自的特点,比较适合在软土地基上修筑.经对青岛创业大道桥的分析,得出了设计参数和桥梁在静力荷载下的受力性能的关系,同时分析了上部结构与下部基础协调作用对...

| Abstract: | Combined deck arch bridge is a type of bridge that is using the deck arch bridge and continuous beam to share the load.This bridge has many benefits for its economical advantages as well as lager bearing abilities,smaller weight,etc.It is easy to resist the push force in the arch feet with prestressing which is good for a soft foundation.This paper discussed this type bridge with the background of Chuangye road bridge in Qingdao,conducted the relationship of parameter to the stress state,and analyzed the co... |
