摘　　要：为进一步推广高填方填石路基在山区公路建设中的应用进展,提升公路建设的绿色化水平,先以高填方填石路基为研究对象,在深入研究其施工及工后阶段沉降机理和沉降影响因素的基础上,明确了路基压实对其整体施工质量的关键意义;再借助DEA方法中的CCR模型,基于有效性指标对提出的4项压实工况备选方案进行了比选,最终给出了最佳的压实工况方案。To further promote the application of high-fill rock subgrade in mountainous highway construction and improve the greening of highway construction,focusing on high-fill rock subgrade,this paper deeply studied the construction and post-construction settlement mechanism and its influencing factors,and clarified the key significance of subgrade compaction to its overall construction quality.Based on effectiveness indexes,four compaction condition schemes proposed in this paper were compared by the CCR model from the DEA method.Finally,the optimal compaction condition scheme was obtained.
