Modelling Subsidence on Buried Pipeline - 01/19/05 12:10 AM
I am trying to model the effects of a subsidence event (due to mine collapse under pipeline) on a buried pipeline. I have modelled the pipeline and buried it and have data on the changed soil profile after the subsidence, but am unsure how to modify the restraints to reflect a lowering of the ground level.
Perhaps I can somehow use the different stiffnesses, K1 & K2, on the bilinear restraints Any help would be greatly appreciated.
