ABSTRACT
This chapter looks at the engineering calculation methods that take into account the impact of earthquakes on the stability of slopes and retaining walls. For in situ loess soils, in calculating the stability of slopes, embankments and retaining walls, it is necessary to consider the effect of sagging properties. In standard seals under water, the specific cohesion of soil undisturbed, because the destruction of the structural connections is reduced. Lower and upper stamps have a perforated surface for the passage of water through the soil. The housing is mounted on a compliant base and thus drastically reduces the degree of heterogeneity of the stress state in the soil sample. The relationship between and the principal stresses for the water-saturated loess soil has a straightforward character. This regularity is also observed in the branch of unloading the soil sample, during the soaking process with a constant value of the lateral pressure of the soil.
