(2008): FE-calculations of stress distribution under prismatic and conical sandpiles within hypoplasticity

Abstract:
The paper deals with the stress distribution beneath prismatic and conical sandpiles. The analysis was performed with the FEM and a micro-polar hypoplastic constitutive model. Several influence factors were studied including the method of pile construction, base roughness, heap inclination, mean grain diameter and initial void ratio of sand. Two methods of sandpile construction were examined: by uniform raining and by centric flow, respectively. The results indicate that the stress distribution under sandpiles is mainly influenced by the construction method. For uniform raining, the maximum stress was observed under the pile centre, while for centric flow, a stress dip was obtained under the pile centre.
