Simulation of strength of waterproof barriers in porous forms

Within the framework of a model of a perfectly plastic body, the strength of a two-layer waterproof barrier adjacent to the trunk of a production well in a porous medium is investigated. The barrier is formed by injecting (with subsequent solidification) synthetic resin into the porous layer through the production well. In the problem parameter space, the domains are determined, in which the strength and yield conditions of the outer and inner layers of the barrier are satisfied.
