The purpose of the work - research, scientific substantiation and prediction of the processes of suffusion, clogging, karst formation, corrosion and leaching, changes of stress-strain state in porous media based on mathematical and computer modeling by building new and improving existing mathematical and computer models, creating information software for automation of solving nonlinear boundary value problems and research of influence of aggressive factors on processes in natural and artificial heterogeneous porous environments, development and substantiation of new methods and algorithms of numerical 5 solution of corresponding nonlinear boundary value problems in domains with moving boundaries and variable mechanical and physico-chemical characteristics. Research method - software environments of object-oriented programming, improved and updated difference methods for numerical solution of the corresponding nonlinear boundary value problems; gridless methods for solving nonlinear boundary value problems in areas with curvilinear, free fixed and moving boundaries; finite element method for boundary value problems with discontinuous solutions; numerical methods for optimizing the search for sliding surfaces with a minimum coefficient of stability.
