Abstract : This article presents a model of flow and transport with filtration in porous media which is used to analyze large-scale grouting tests. A program based on the finite element method is developed to solve the model equations; a particular attention is paid to inherent issues of transport problems. The analysis of these tests aims at providing insights on the propagation patterns associated to the injection of cement-based grouts in sand. To apprehend particular features that characterize field injections, the experiments are performed by using a tube-a-manchette and a patented grout. Finally, the role of filtration during the tests is discussed.
