【 摘 要 】

The article presents the formulation and solution of quantifying the speed of the finite width foundation settlement due to viscoplastic or elastic-plastic extrusion of the weak soil layer from compressible base by analytical and numerical methods. During numerical simulations were used the finite element method with Mohr-Coulomb model (MC) and the model of Soft Soil Creep (SSC). According to the results of analytical solution were obtained the formulas to determine an initial ultimate load and a value and the foundation settlement speed.
