The study was conducted to determine the main technical reasons for the fall of the pile-driving machine that occurred when driving-in of piles in the immediate vicinity of the slope. As a result, slope stability of the soil in the process of driving-in of reinforced concrete piles near the slope crest of the underlying pit was determined. The calculations were performed using the following four well-known methods: methods of Fellenius, Krey, Terzaghi, Chugayev. The loss of stability of the soil was caused by the imbalance of external and internal forces (the presence of construction equipment and stored materials near the slope and its dead load). The calculations were performed for six loadcases of the earth wall. The article presents in detail the case in which the slope collapsed. The importance of the results for the construction industry lies in the need for a comprehensive study of safety issues at all stages of the life cycle of construction projects, starting with the preparation of a design assignment, surveys, design, construction, operation, repair, reconstruction, etc.
