| 摘 要： | 用常规击实方法制备不同夯击能量下的土样,来研究击实黄土的工程性质.试验结果表明,击实黄土的压缩模量、粘聚力及内摩擦角随击实功的增大而增大;不同击实功下土样的强度随龄期呈增长趋势,但其增长幅度与试验过程中的压应力大小有关;同一龄期土样的粘聚力随击实功变化幅度较大,而内摩擦角随击实功变化幅度较小.

| Abstract: | This paper fabricates soil samples by normal compaction in different compactive effort to study the engineering mechanics properties of the compaction loess.The test results show that the compression modulus,cohesion,angle of internal friction of compaction loess increase with the compactive effort,and the strength of soil samples appears growth trend when the age increases,but the increasing extent is related to the compression stress in test procedure;the cohesion of the soil samples at the same age change quickly with the compactive effort,but the angle of internal friction changes slowly. |
