【摘要】 为解决传统清淤换填处理公路超软土地基时产生大量废弃土、环境破坏等问题，以公路工程为应用场景，对路堤荷载下超软地基的就地固化处理展开研究。通过分析技术原理，从处理范围确定、配合比设计、沉降与稳定性计算等方面构建设计方法，同时明确包含前期准备、土样检测、配比试验、搅拌固化、平整预压养护及质量检验的施工工艺，并结合工程实例验证该方法的有效性，提出一套系统的公路超软土地基就地固化设计与施工方法，以期为公路工程中超软土地基处理的相关工程提供参考。更多还原

【Abstract】 To address the issues of significant waste soil generation and environmental damage associated with traditional dredging and replacement methods for treating ultra-soft soil foundations in highways, this study focuses on the in-situ stabilization of ultra-soft ground under embankment loads within the context of highway engineering. By analyzing the technical principles, a comprehensive design methodology is established, encompassing the determination of treatment scope, mix proportion design, and calculations for settlement and stability. The construction process is clearly outlined, including stages of preliminary preparation, soil testing, mix proportion testing, mixing and stabilization, leveling-preloading-curing, and quality inspection. The effectiveness of this method is validated through a practical engineering case study. This paper proposes a systematic approach for the design and construction of in-situ stabilization of ultra-soft soil foundations in highway projects, aiming to provide a reference for similar engineering applications.更多还原
