Ome analysis of the stress-strain state of earth dams taking into account their own weight

Abstract

The paper is devoted to static problems of studying the stress state of earth dams, taking into account their own weight. A method of static problems is developed to determine the stress-strain state of earth dams. An algorithm for solving problems and calculation formulas based on the finite difference method were developed. The advantage of the developed method is the implementation of complex strain models considering structural changes in soil media. The problems of the stress state of the earth massif and the earth dam are solved by two methods, using the finite difference method and the Plaxis program based on the finite element method. The distribution of the stress state over the earth massif and over the cross section of the dam under the action of its own weight is determined using the example of the Charvak dam. The results obtained by the finite difference method and by the Plaxis program based on the finite element method are compared.
