Mass transport in an excavation using a ternary Theory of Porous Media model

Abstract This paper tries to simulate a hydraulic failure by using a ternary, saturated, quasi‐static Theory of Porous Media (TPM) model. The concept of a hydraulic failure is shortly explained and the derivation of the TPM setup including the limitation of the volume fractions is depicted. A schematic excavation with a sheet piling is used to test the created model and prove the general feasibility of the idea.
