Laboratory Model Test and Numerical Analysis of Bearing Capacity of Rigid Strip Footing on Slope

抄録

This paper focuses on the estimation of bearing capacity of rigid strip footing on slope by performing a number of laboratory model tests and the numerical analysis. The laboratory model tests, including unreinforced and reinforced subsoil, are carried out using three types of subsoil. A numerical procedure is proposed which is based on a smeared shear band approach and a modified initial stress method, employing Mohr-Coulomb yield criterion with a simple plastic flow rule. The proposed procedure is capable of estimating not only the bearing capacity for natural subsoil, but also under complex conditions, for example, reinforced subsoil considering stiffness and deformation of materials. In most cases, a fairly good agreement is obtained between the experimental and analytical results.
