Özet

This paper illustrates the use of Smoothed Particle Hydrodynamics (SPH) technique to compute the bearing

capacity of shallow foundations and establish their failure mechanism. SPH is a numerical method based on a

Lagrangian formulation to solve partial differential equations by discretizing the computational domain with a set

of particles that have field variables such as mass, and density. SPH is a meshless method and is not affected by

the particles’ arbitrariness due to its adaptive nature, and it can naturally handle problems that are caused by large

deformations. Non-associated Drucker-Prager model is implemented into the model to simulate the soil behavior.

The computed values are then compared with PLAXIS 2D finite element results. Agreements of the results of

these two methods show that SPH is potentially a promising method for geotechnical problems experiencing large

deformations and mesh distortions.
