Modern hydraulic engineering requires high reliability and safety of structures in challenging hydrogeological conditions, including heterogeneous soils and complex mechanical interactions. This study presents a numerical simulation of the stress-strain state of a hydraulic structure with a retaining wall based on layered heterogeneous soils. The relevance of the study stems from the need to improve the accuracy of predicting the behavior of soil masses and reduce the risk of accidents for soil structures on complex terrain, which is confirmed by the use of modern finite element methods and modeling of the interaction between the structure of the foundation soils of the structure and various elements of the structure itself. The analysis revealed that the maximum total displacement of the retaining wall during the construction phase is 0.026 m (26 mm), which is significantly lower than the permissible values (100–150 mm according to SP 22.13330.2016), ensuring the required stability of the structure. The maximum pore pressure in the foundation was determined to be -433.71 kN/m² at a depth of 62.7 m, indicating the high bearing capacity of the soils. Modeling revealed stress concentration zones at the wall base with a maximum value of 1027.66 kN/m², requiring the application of appropriate design solutions to improve the structure's reliability. The practical significance of this study lies in improving the accuracy of stress-strain state assessments for the structure itself in the presence of heterogeneous foundation soils, thereby reducing the risk of accidents, optimizing design solutions, and developing recommendations for the operation and modernization of similar facilities.
