摘要
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 gradeⅢself-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.
