Abstract.<\/strong> This article presents a study aimed at solving the problem of constructing bridges on soft soils under conditions of variable groundwater levels (GWL) and seismic impacts. The study addresses questions about the quantitative impact of GWL fluctuations on the stress-strain state of the structure and the effectiveness of the proposed geotechnical solutions. A comprehensive analysis was performed using finite element numerical modeling in the Plaxis 2D software package. The study was conducted using a bridge crossing in the village of Troitskaya in Krasnodar Krai, taking into account two groundwater levels and a seismic impact with an intensity of 8. It was found that raising the groundwater level leads to an increase in bending moments in the central zone of the pipe by 4,6\u20135,6 % and a decrease in the peripheral zone by 7,6\u20138,0 %. Stresses under the pipe in the central zone decrease by 13,6\u201320,9 %, while at the edge of the pipe they increase by 4,6\u20135,6 %. The developed geotechnical solutions, including replacing soft soil with rubble stone, demonstrated high efficiency: maximum stresses do not exceed 10 % of the standard bearing capacity of the foundation. A key result is the established multidirectional influence of the groundwater level: water saturation of the central part of the foundation leads to unloading of the structure (reduction of moments and stresses), while in the perimeter zones an increase in contact stresses is recorded, which requires mandatory consideration in the design. The identified quantitative patterns make it possible to predict changes in the stress-strain state of the foundation and structure during seasonal fluctuations in groundwater levels, as well as to justify the need to strengthen weak soils by replacing them with high-modulus materials.<\/p>\n
