Abstract: This study considers the problem of soil slope stability near the hydraulic structures. This problem is important because there are requirements for ensuring the sustainability of the constructed and finished objects and there is methodology and results of instrumental determination of the disturbed massif condition with the use of geodetic methods the studies determined the value of benchmarks movements in soil. The problem of soil slopes stability has always been the most urgent as the soil slopes are constantly encountered in the construction of hydraulic complexes, hydroelectric power stations, roads, civil facilities, etc. They exist in open excavation and embankment of the soil or in a cut and fill. Variable external conditions (humidity, temperature) affect the soil slopes they transform physical and mechanical characteristics of the soil and it clearly affects their stability.
