摘　　要：路基稳定性是影响道路质量的重要因素,土方路基的稳定性主要取决于压实工艺。目前施工单位主要采用标准击实试验来获得最大干密度和最佳含水量,并以此计算路基压实度作为压实工艺的评价标准。因此,控制标准击实试验的试验过程,保证试验结果的准确性,是确保路基压实度满足要求的重要手段。故从材料取样、试样制备、含水量测定及试验结果处理等几方面入手,探讨了标准击实试验的控制方法。The stability of subgrade is one of important factors that influence the quantity of the road.The stability of earth-filled subgrade depends on the process of compaction.At present,the maximum dry density and optimal water content are obtained through standard compaction test,and the compaction degree is used as evaluation criterion of the compaction of the earth-filled subgrade.Accordingly,in order to make compaction degree satisfy the desire of construction,it is important to control the test procedure of standard compaction test to ensure the accuracy of the test results.In the paper,the method of sampling and specimen preparing of the earth-filling,test method of water content and the analysis of the test results are discussed for controlling the standard compaction test effectively.
