摘要
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。
The effect of backfill soil gravity amplified coefficient K on the design of highway reinforced concrete slab culvert is explored,and considering the excess compressive stress on the subbase,the concept of proper compation of soil is presented.During the design of reinforced concrete slab culvert structure,optimizing the foundation and application of the foundation trench installation technology are suggested to minimize or eliminate the effect of backfill soil gravity amplified coefficient K on the design of highway culvert.
