Strength of earth dams considering the elastic-plastic properties of soils

The article provides a detailed review of well-known publications devoted to studying the stress state and dynamic behavior earth dams, taking into account elastic elastic-plastic properties soil. To assess stress-strain considering soil under action static loads, mathematical model was developed using principle virtual displacements. A technique, algorithm, computer programs were for estimating dams finite element method variable elasticity parameters. test problem solved adequacy models reliability algorithms, programs. Pskem dam, 195 m high, studied calculation methods, body forces various levels filling reservoir with water. It established that an leads sharp change in especially upper prism core changes intensity normal stresses, which can lead violation integrity dam.
