Abstract
The article uses geophysical studies of the protective dam of the valley of the river Psekups, which made it possible to clarify the boundaries of engineering-geological soil elements and determine the dynamic properties of the dam and foundation, which were used in the calculation of the barrier dam for seismic loads. It should be noted that the water level in the Krasnodar reservoir varies significantly throughout the year; its minimum value, as a rule, occurs in the autumn-winter period, and the maximum – in the spring, this significantly affects the value of seepage flow through the body of the protective dam of the Krasnodar reservoir in the valley of the river Psekups and on the position of the depression curve. The main purpose of the work is to substantiate the stability of the protective dam of the Krasnodar reservoir in the valley of the river Psekups after a long operation and due to an increase in the normative seismicity of the territory. It is established that the discrepancy of one of the first approximate methods for calculating the stability of slopes according to V. Felenius with those performed in the course of the study are within the error of the initial data obtained in the field a comparison of the calculation results using a software package using the four most recognized methods in scientific, design and construction organizations in Russia – the Cray method, the Terzaghi method, the VNIIG method, the Mozhevitinov method and the method according to SP 39.13330.2012 -was carried out.
