The load-bearing characteristics of bridge pile foundations under soft ground conditions are complex, directly impacting the safety and stability of bridge projects. This paper focuses on this issue, delving into the interaction mechanisms between piles and soil, and clarifying that the load-bearing characteristics of pile foundations are influenced by multiple factors, including pile material, geometric dimensions, and the physical and mechanical properties of the soil. To address these influencing factors, the paper proposes optimization design methods, such as selecting appropriate pile types, optimizing pile length and diameter, and employing composite foundation treatment technologies. It also outlines key construction points to ensure the effective implementation of the optimization design. The research findings provide a scientific basis for the design and construction of bridge pile foundations in soft ground conditions, which is crucial for enhancing project quality and reducing construction costs.
