Abstract:

One of the most common methods to measure soil strength in-situ is by cone penetrometer. This paper is about the development of a 3 dimensional (3D) discrete element model (DEM) for simulation of the soil-cone penetrometer interaction. To simulate cohesive soil the Hertz-Mindlin with bonding contact model was used in EDEM 2.7 discrete element software. The parameters were calibrated to real test result and after that the effect of the model dimension (namely the diameter of the cylinder) on soil penetration resistance was analysed. The results of the calculations were very similar to the real soil penetration resistances therefore the model can be used to simulate the cone penetrometer in-situ test. Another result of the paper that a suggestion for proper model size is given in soil-cone penetrometer discrete element simulations.
