摘　　要：为了研究浅层粘在垂直荷载作用下地基的破坏机制和极限承载力,不考虑土体自重,采用关联流动的Mohr-Coulomb屈服准则,本文主要分析在模拟的柔性基础中,给粘土层中施加一个垂直载荷,研究它的静态响应和崩塌载荷。粘土采用弹-完美塑性材料模型描述,并使用平面应变中的Mohr-Coulomb屈服准则,其响应则使用非对应流动定律来研究。In order to study the failure mechanism and ultimate bearing capacity of shallow clay under vertical load, without considering the self-weight of soil, the Mohr-Coulomb yield criterion of correlated flow is adopted in this paper, which is mainly analyzed in the simulated flexible foundation. A vertical load is applied to the clay layer, and its static response and collapse load are studied. The elastic-perfect plastic material model is used to describe the clay, and the Mohr-Coulomb flexion criterion in plane strain is used to study the response of clay by non-corresponding flow law.
