摘　　要：为研究湿陷性黄土路基填筑技术,结合工程实践,详细介绍了湿陷性黄土路基病害种类及产生原因,探讨了冲击碾压法及强夯法两种湿陷性黄土路基填筑工艺,并采用两种施工方法对试验段进行填筑,最后对填筑完成后的试验段相关性能指标进行检测。结果表明:两种施工工艺下试验段路基平整度均能满足规范要求,采用冲击碾压法施工工艺下试验段路基平整度较好,而采用强夯法施工的试验段路基压实度更佳。For the study of collapsible loess roadbed filling technology, combining with the engineering practice, a detailed introduction of collapsible loess roadbed diseases and causes, and discusses the impact compaction method and dynamic compaction method two kinds of collapsible loess roadbed filling process, and adopts two methods of the construction of test section filling, and finally to fill after the completion of the test section of the relevant performance indicators for testing.The results show that the test section of roadbed roughness under two kinds of construction technology can meet the specification requirements, the impact compaction method is adopted under the construction technology of test section roadbed flatness is better, and the dynamic compaction method construction of subgrade compaction degree test section is better.
