针对山西省寿阳县至太原市迎泽区山区Ⅲ级自重湿陷性黄土区域高填方路基施工中地形复杂、机械作业受限、雨水影响等难题，研究优化机械化施工工艺。研发“模块化机械组合”方案，构建“智能强夯-精准拌和-智能碾压”技术链，包括强夯能量动态调控、水泥土拌合物联网平台、压实质量数字孪生系统等创新技术。工程实施表明，湿陷系数降低62.5%，改良土压实度标准差缩减66.7%，工后沉降收敛时间缩短40%，实现施工效率与质量双提升。

Aiming at the problems such as complex terrain, limited mechanical operations, and the influence of rainwater in the construction of high-fill roadbeds in the mountainous area of grade III self-weight collapsible loess from Shouyang County, Shanxi Province to Yingze District, Taiyuan City, this study optimizes the mechanized construction process. Develop a "modular mechanical combination" solution and build a technology chain of "intelligent dynamic compaction-precise mixing-intelligent rolling", including innovative technologies such as dynamic regulation of dynamic compaction energy, an Internet of Things platform for cementing soil mixing, and a digital twin system for compaction quality. The implementation of the project shows that the collapsibility coefficient has decreased by 62.5%, the standard deviation of the compaction degree of the improved soil has reduced by 66.7%, and the post-construction settlement convergence time has shortened by 40%, achieving a dual improvement in construction efficiency and quality.
