UNDRAINED BEARING CAPACITY OF EMBEDDED STRIP FOOTINGS UNDER VERTICAL AND HORIZONTAL LOADS
Résumé
This paper is concerned with the undrained bearing capacity of embedded strip footing under inclined loading (i.e. combined
vertical and horizontal). A series of numerical computations using the finite-difference code Fast Lagrangian Analysis of
Continua (FLAC) was carried out to evaluate the failure envelopes in vertical force – horizontal force (V-H) plane, using both
probe and swipe analyses. The adopted approach involves a numerical solution of the equations governing elasto-plastic soils.
The soil is modeled by an elasto-plastic model with a Tresca criterion. The results are presented in terms of the failure
envelope in vertical and horizontal loading plane.
