探讨《公路涵洞设计细则》中关于填土重力增大系数K对公路钢筋混凝土盖板涵设计的影响,针对基底面上压应力过大的问题,提出填土适当压实度概念,在公路钢筋混凝土盖板涵结构设计时,建议优化基础采用基槽法安装技术,从而减小或消除填土重力增大系数K对涵洞设计的影响。 This paper discusses the influence of filling factor K on the design of highway reinforced concrete culverts and culverts in the detailed design rules of highway culverts. According to the problem of excessive compressive stress on the foundation surface, In the design of concrete culverts, it is suggested to optimize the foundation with the installation of foundation trough method so as to reduce or eliminate the effect of fill gravity increase factor K on culvert design.
