摘　　要：本文通过西三公路施工,较系统地总结了路基土方的压实工艺,将压实工艺与路基的质量间相互关系作了系统分析,并通过填方路堤的沉降量观测,以及承载板、弯沉值的测试结果,说明采用重型击实标准的优越性,从而实现了当年填筑路基(特别是高路堤),当年铺筑路面,当年通车,当年收益的快节奏施工。This paper reviews the workmanship of subgrade soil compaction in the construction of Xi'an-Shanyuan national high-grade highway and the correlation between the compaction workmanship and the subgrade quality is systematically analyzed.The superiority of adopting a heavy compaction standard is justified by the settement observations of the embankment,the plate loading tests and the deflection measurements,so that the pavement can be constructed on the embankment,espe- cially the high embankment in the same year to expedite the opening to traffic.

关 键 词：岩土 重型击实标准 含水量 强度
