Model of Bentonite Swelling Solved as a Contact Problem
Original language description
We deal with a modelling of bentonite behavior during the saturation process in a high level waste repository. Our work is motivated by a potential damage of the bentonite barrier due to non-uniform swelling and the model problems are formulated based onthe configuration of the BRIE experiment modeled as Task 8 within the Task Force on Engineered Barrier System. The swelling problem is an extention of the original modelling task of the water transport only. The main challenge is how the gap between therock and bentonite (often neglected in models) controls the swelling and the resulting stresses in bentonite. While in the fully confined case, the water inflow causes immediate build-up of the swelling pressure, in the real case the free swelling can occur in the first stage until the full contact between the bentonite and rock. Together with expected non-uniform water inflow (from a single fracture), the process can be quite complex. We developed a solution by means of a contact probl
