Elastic-Plastic Large Deformation Response of Clay to Footing Loads,

摘要

An analytical study of the static response of a homogeneous clay stratum to footing loads is presented in this dissertation. Clay is modeled as a linear elastic-perfectly plastic material with the Drucker-Prager yield condition and associated flow rule. The effect of large deformations on the response of the clay is included in the analysis. Both drained and undrained analyses are considered. In particular a single,strip surface footing bearing on a finite stratum of clay is considered. The footing is assumed to be rigid and the interface between the footing and soil may be either smooth or rough. The base of the soil stratum is rigid and perfectly rough. A plane strain condition is assumed. Numerical techniques are utilized to solve this elastic-plastic,large deformation boundary value problem. (Modified author abstract)
