Purpose. The purpose of this work is to develop a research methodology, on the basis of which it is possible to perform the selection of the composition of the solution with the determination of the physicomechanical characteristics of both the thixotropic and hardened solution, as well as to determine the effect of the number of individual components on the properties of the mortar mixture and the protective screen based on it. Methodology. The research method is to use an adapted plan of experimental-statistical modeling to solve specific problems, namely when creating a reliable, inclined filtering screen inside the sand massif under conditions when technological parameters change. Technological research method: analytical and experimental. Findings. To solve the problems of analysis and optimization of the factor systems under study, the theory of mathematical modeling was used in the work. At the same time, experimental-statistical regression models are considered, which show how the indicator under study (y) changes as the relevant factors change. Originality. According to the results of the work, a technique has been obtained that allows, with a minimum amount of materials and experiments, to obtain the physicomechanical indicators of solutions and a protective soil-concrete screen based on them.
