Abstract
In order to study the stress transfer law of loess under different compaction conditions,the influence of different compaction conditions on stress transfer of loess was analyzed by measuring hammer impact force,soil bottom pressure and air volume ratio based on conventional compaction test and single click compaction test.The results show that different water content has a significant effect on the stress transfer of loess.Moderate water content can improve the compaction effect,while too low or too high water content may affect the efficiency and stability of stress transfer.In the conventional compaction test,the optimal water content is 12.8%,and the corresponding dry density is 1.96 g/cm3.In the single click real test,the optimal water content was 13.16%and the corresponding dry density was 1.91 g/cm3.In order to ensure good water stability after compaction,the soil voidage is calculated and 4.6%is proposed as an additional index of compaction quality.关键词
