| Abstract: | Prestressed concrete continuous box girder and steel-concrete composite girder are more and more adopted in construction of highway and railway. They are also widely applied in construction of Beijing-Shanghai High-speed Railway Line. This paper analyses the structure, dynamic features, construction, application and economic characteristics of these two kinds of girders, for reference to survey and design of similar works. |
