ABSTRACT
The paper deals with use of the meshless method for subsoil bearing capacity analysis. There are many formulations of the meshless methods. The article presents the Meshless Local Petrov-Galerkin method (MLPG) – local weak formulation of the equilibrium equations. The main difference between meshless methods and the conventional finite element method (FEM) is that meshless shape functions are constructed using randomly scattered set of points without any relation between points. The shape function construction is the crucial part of the meshless numerical analysis in the construction of shape functions. The article presents the solution of the Prandtl ultimate load of the fully saturated soil strip.
Keywords:meshless analysis,meshless Petrov-Galerkin method, bearing capacity
