Calculation method of fastening the upper slope of the land bund for erosion and strength

To protect the slopes of the ground dam from the devastating effects of wind waves, ice, water flow, precipitation and other factors, a number of engineering measures are provided. Based on this, an engineering decision is taken on the choice of materials for fastening structures, as well as methods for calculating their stability. When calculating the stability of the upper slope, two cases of a combination of loads and impacts are mainly considered. One of them is the reduction of the water level in the reservoir with maximum speed, and the other is the case when the water level in the reservoir is at the lowest operational level. The article investigates the processes of sliding of natural slopes of the upstream dam. Taking into account the combined action of the forces of filtering, weighing and vapor pressure, as well as the force of hydrostatic pressure to the level of dead volume. The equation for the stability coefficient of a circular-cylindrical slip of a uniform natural slope of the upstream dam has been obtained.
