冲击压实旧水泥混凝土路面路基的有限元分析

Analysis of old cement concrete pavement and roadbed of impact compaction by fem

针对冲击压实技术在旧水泥混凝土路面修复工程中的应用，采用有限元方法研究冲击压实过程中旧水泥混凝土路面结构及路基的变形及应力分布特征。研究结果可为冲击压实机理的分析及指导现场施工提供理论依据。

Taking the old cement concrete pavement with inpaet compaction technology on rehabilitation project as an example, the stress an deformation characteristics of the old cement pavement structure and thor soil subgrade in the process of impact compaction are studied usin the finite element method. The results obtained in this paper can provide reference for the study on the mechanism of impact compaction an for the the impact compaction practice on site.
