| 摘 要： | 利用弹性非线性理论和Mohr-Coulomb破坏准则，采用有限元方法对钢筋混凝土涵洞顶部垂直土压力进行分析，主要讨论了洞顶垂直土压力与地基弹模、边坡、上覆土体厚度等之间的关系，所得的土压力系数在0．6～1．4之间连续变化。

| Abstract: | In this paper, elastic-nonlinear theory and Mhor-Coulomb failure criterion are used to analyse the vertical loading pressure on top of ferroconcrete culvert by FEM,and the relations between the vertical pressure and foundation modulus,slope,and thickness of soil filled are discussed mainly. Finally it is presented that the coefficient of loading pressure, namely the value of,is from 0.6 to 1.4 continuously. |
