Pullout Capacity of Model Piles in Sand
A large scale experimental program using vertical and batter model piles in sand subjected to pull out loads has been carried out in a model tank of size 1m x 1m x 1m. Mild steel pipes of varying diameters, lengths, and shapes are used as model piles. A poorly graded river sand having specific gravity G= 2.67, Uniformity coefficient= 3.53, emax = 0.81, emin = 0.54 has been used as foundation me...
متن کاملStructure of some sand piles model
spm (Sand Pile Model) is a simple discrete dynamical system used in physics to represent granular objects. It is deeply related to integer partitions, and many other combinatorics problems, such as tilings or rewriting systems. The evolution of the system started with n stacked grains generates a lattice, denoted by SPM(n). We study here the structure of this lattice. We rst explain how it can ...
متن کاملStructure of Stable Sand Piles Model
In this paper we study a variant of the Sand Piles Model, where the evolution rule consists of the falling down of one grain to a random column and an avalanche to reach a stable configuration. We prove that the infinite set of all stable configurations have a lattice structure which is a sublattice of Young lattice. At the end, based on a discussion about avalanches, we construct a generating ...
متن کاملInteractive Terrain Simulation and Force Distribution Models in Sand Piles
This paper presents an application of Cellular Automata in the field of dry Granular Systems modelling. While the study of granular systems is not a recent field, no efficient models exist, from a computational point of view, in classical methodologies. Some previous works showed that the use of Cellular Automata is suitable for the development of models that can be used in real time applicatio...
متن کاملPerformance of helical piles in oil sand
The results of a comprehensive pile load-test program and observations from field monitoring of helical piles with either a single helix or double helixes installed in oil sand are presented in this paper. Eleven full-scale pile load tests were carried out including axial compression, uplift, and lateral load tests. The results of the full-scale load tests are used to develop a theoretical desi...
