| 摘 要： | ８０年代末开始，钢管混凝土在我国公路和城市拱桥中得到应用，发展很快，在全国已建工程达一百多座。跨度最大的有乌江二桥，Ｌ＝３６０ｍ，采用了５－４管集束式拱肋和四川万县长江大桥，Ｌ＝４２０ｍ，采用了钢管混凝土劲性骨架箱形截面拱肋。在拱桥的推广应用中，出现了很多创新工作，对钢管混凝土在桥梁工程的应用中作出了贡献。同时，在某些设计中也还存在一些不足之外，作者就这些问题提出了建议，供有关方面参考。

| Abstract: | Since the late of 80's, the CFST structures had been adopted in the highway and city arch bridges, the development is very rapid. There were over 100 bridges through the country. The largest span belongs to the Wu-river 2nd bridge, L = 360m, adopted the 5 -4 tubes gathered bunch arch ribs, and the Yangzi river bridge of Wan Country, Sichuan Province, L =420m, adopted CFST framework box cross - section arch ribs. In the application, there are many creative works, which make a contribution to the application of CFST for bridge engineering. But, there are several problems in the designs also. About. these problems author gives some suggestions, which are available for reference. |
