| 摘 要： | 对上埋式涵洞垂直土压力的计算,文中主要考虑填土性质的影响,通过假定洞顶土柱体两侧摩擦力达到最大静摩擦力,采用朗肯主动土压力作为侧压力,得出一种简化计算公式。经分析比较,其形式与荷载规范中的公式一致,计算结果在埋深较浅时与规范方法及其他方法相近,有一定的实用性。

| Abstract: | For calculating vertical soil pressure on culvert under embankment,this article introduces one kind of simple and convenient simplified calculating formula by supposing that when the fraction force of two sides of pillar on the top of culvert reaches the biggest and Rankine's active soil pressure is taken as supplementary pressure.Through the analyzing and comparisons,its form is identical with the formula in specifications for load design.The result of calculation is similar with other ways.It has some practical affect. |
