Soil–water interaction

Soil–water interaction exists in many environmental and civil engineering problems, such as landslides induced by rainfall, fluidisation and sedimentation processes in submerged slopes, internal erosion in dykes, scouring around offshore structures, settlement due to consolidation processes and installation of piles in saturated soils. Modelling these processes is challenging due to soil–water coupling and large deformation.
MPM is a point-based numerical method capable of modelling large deformations and recently, within the framework of the MPM Research Community, it has been extended to cope with complicated soil-fluid interactions.
This training course focuses on presenting those MPM formulations cable of simulating the interaction between soil and water phases. Two different approaches will be addressed. In the first one, a single set of material points describes the behaviour of saturated porous media understood as a mixture of solid skeleton and pore fluid. The second approach describes the movement of each constituent (i.e. solid and fluid) individually by means of two sets of material points, thereby enabling the simulation of free water and the in and outflow, as well as fluidisation and sedimentation processes.

Tutored exercises

Course participants will gain experience as users of the MPM Software developed by the MPM Research Community.
During training lectures, the attendees will learn first-hand capabilities of MPM by means of a set of practical exercises that will be undertaken following a tutorial specially designed for the course:
– Dynamic consolidation problem
– Dam break problem
– Seepage flow inducing slope liquefaction
