| Abstract: | Combined with construction practice of the passenger dedicated railway line,aiming at the new bridge structure and constuction technology,the characteristic and main point of some new bridge stucture were analysed,such as the post-tensioned prestressed concrete simple supported box beam,two-way prestressed concrete simple supported fabricated T beam,RC rigid framed continuous girder and steel-concrete composite continuous girder.The role of these new technology was summarized based on the construction of passenger dedicated railway line,and was put forward.Some proposals to the structure design and construction of passenger is helpful to railway line bridge. |
