高速公路路基压实标准的施工控制研究

公路路基的强度和稳定性在很大程度上取决于路基填料的性质及其压实的程度。只控制土体压实时的干密度，即采用现行干密度比的压实度控制标准，是不能完全保证路基的强度和稳定性的。通过对低液限粉性土不同压实控制标准的研究．对路基压实的孔隙率控制方法与现有的压实度控制方法进行比较，不仅可确定合理的压实标准，而且证明孔隙率控制法不仅简单易行，而且是切实可行的。

Construction Control of Expressway Subgrade's Compaction Standard

The intensity and stability of subgrade relates to the certain filling of subgrade＇s property and the degree of compaction in most degree. Only controlling the dry density under compaction, using actual compact-control method, can not assure the intensity or stability of subgrade absolutely. Through researching on low liquid limit soil subgrade under different control standards, comparing the porosity control method with the actual compaction method, reasonable compaction standard is established, it is testified that the porosity control method can be not only simply performed but also feasible in compaction control of subgrade.
