Abstract

The settlement problem of soft soil foundations is one of the common and serious challenges in expressway construction. This paper studies the prediction methods for subgrade settlement of expressways on soft soil foundations, evaluates several commonly used prediction technologies, and compares the corresponding reinforcement techniques. By analyzing the influence of different reinforcement methods on subgrade settlement, optimization schemes most suitable for different geological conditions are proposed. Combining appropriate reinforcement measures with settlement prediction technologies can significantly improve the stability and safety of expressways. This study provides theoretical support and practical guidance for settlement control and reinforcement in the construction of expressways on soft soil foundations.
