摘要
某城市90 m钢箱拱肋提篮系杆拱桥,主梁采用钢混叠合梁,拱肋截面高度和宽度在空间同时变化,并采用无柔性系杆体系和减隔震抗震体系。通过对该桥技术特点介绍和计算分析,可为同类型桥梁设计提供一定的参考。
There is a 90-metre steel-box arch-rib basket bowstring arch bridge in a city.Its main girder is a steel-concrete composite girder.The height and width of its arch rib section vary synchronously in space.The inflexible bowstring system and seismic isolation system are adopted.The introduction,calculation and analysis of its technical characteristics can provide a certain reference for the design of the similar bridges.
