摘要
波形钢腹板桥是采用波形钢腹板代替传统的预应力混凝土箱梁中混凝土腹板的一种组合结构桥梁,其结构的主要特点是减轻主梁的自重,提高混凝土主梁的预应力效率,减少现场工作量,降低工程成本。近年来,波形钢腹板桥梁在世界各国尤其在日本得到快速发展,该文介绍了波形钢腹板桥的技术特点,并介绍了国外,尤其是日本的波形钢腹板桥梁的工程实例,以供参考。
Bridge with corrugated steel webs is a kind of composite-structure of steel and concrete using the corrugated steel webs instead of concrete webs for conventional prestressed concrete box girders. This structure is characterized by reduction of dead weight of main girder,improvement of prestressed e^ciency of concrete girder and reduction of on-site work and construction cost. In recent years, the box girder bridges with corrugated steel webs have developed quickly all over the world, especially in Japan. In this paper,it presents the cases of bridge projects with corrugated steel webs in foreign countries, such as France, Japan, Germany and Korea.
