Or maybe even look at the compressive stresses in the soil directly in front of the pile?
#How to scale data from plaxis 2d how to#
I am not 100% sure how to find the resistance of the soil along the piles, perhaps look at the compressive forces in the pile with depth? Therefore you must use your own engineering judgement to distinguish when your single piles and pile groups have failed.Īs regards each individual pile, you may have to consider the proportion of the total pile group load taken by a particular pile and plot against pile displacement and again decide yourself at what point the pile fails. All plaxis will do is give you the load displacement response of your piles. PLAXIS 3D Foundation does not give you a direct answer if that is what you mean. Depending on the length/diameter ration of your SC, your SC will have bulging or punching failure.Īpologies for this late reply, I have been busy with my own thesis! Bulging will also depend on vertical refinement. Make sure to refine mesh around stone column. (note:phases 1-3 should be 'plastic' as opposed to consolidation phases) 100kpa (you must have selected a udl on the top of your soil model in the 'model' window beforehand, indicated by hatched lines).Ĥth phase: consolidation using 'ultimate time' or 'minimum excess pore pressure'. double click on hatched lines and select load you wish to apply e.g. You can set the depth of the SC using workplanes.Ģnd phase: Change soil properties within massive circular pile to properties of stone (this is done in calculations, not in the soil model!!)ģrd phase: Turn "on" udl on soil surface, i.e. The massive circular pile should obviously be the same diameter as the SC you wish to model. Yes, I suggest you use massive circular pile (without interfaces to simulate the interlocking between the stone and soil).
