Soft soil foundations are widely distributed in coastal and inland lake areas, where their unique physical and mechanical properties pose significant challenges in engineering construction. As a critical factor affecting the stability and settlement deformation of soft soil foundations, groundwater level changes trigger complex physical processes that alter the stress state and engineering characteristics of foundation soils. By integrating theoretical analysis, numerical simulation, and practical case studies, this study establishes a quantitative relationship model between groundwater level changes and soft soil foundation settlement. This provides solid theoretical and technical support for predicting foundation settlement and formulating reasonable foundation treatment and deformation control measures in engineering practice.
