| 摘 要： | 土的最大干密度和最佳含水量是土方路基施工的一项关键指标.通过对自由排水粗粒土最大干密度试验方法的研究,提出了使用表面振动压实仪法的干土法难以得出土的最大干密度,而湿土法不仅能得出土的最大干密度,还能得出土的最佳含水量的观点,可为试验人员合理选择试验方法提供指导.

| Abstract: | The maximum dry density and optimum moisture content of soil are key indicators for earth- work embankment construction. Through the research on test methods of maximum dry density of free drainage coarse grained soil, it is proposed that it is difficult to get the maximum dry density of the soil by means of the dry soil method of surface vibration compaction meter method; but by means of the wet soil method, we can not only get the maximum dry density, but also get the optimum moisture content. The research may provide guidance for testers and help them choose test methods rationally. |
