摘要
传统钢筋混凝土涵洞在运营后期常因结构刚度较大、不能适应地基变形而带来一系列问题,公路波纹钢管涵洞能较好解决这一问题。此外由于施工便捷、经济实用等优点,公路波纹钢管涵洞越来越受到行业的关注,但是由于国内尚无相应完整的设计规范体系,在一定程度上限制了公路波纹钢管涵洞的应用。在综合比较了国外波纹钢管涵洞设计规范的计算公式及参数取值的基础上,结合国内结构材料相关取值,论证了国外波纹钢管涵洞设计规范在我国具有适用性,并推荐采用加拿大公路桥涵设计规范。
Problems come at the later operation period for the traditional reinforced concrete culverts with greater structure stiffness and the disability of being adapted to the deformation of foundation, which can be solved with highway corrugated steel pipe culverts. Additionally, more and more attention was paid to corrugated steel pipe culverts because of their convenient construction, economical efficiency and practicability. Domestic design specification system for highway corrugated steel pipe culverts is not completed, which limits their development of application in some degree. The calculation formulas and values of parameters in foreign corrugated steel culvert design codes were investigated in the paper. The feasibility of these foreign codes in China was confirmed with the consideration of domestic material properties. Canadian Highway Bridge Design Code was recommended.
