【摘要】 通过对粗粒土不同级配的渗透破坏坡降控制性试验研究,发现粗粒土的渗透破坏坡降与其级配在不同范围内存在一定的相关性联系。并通过试验得出,含一定量细粒组分且级配良好的粗粒土渗透破坏坡降比级配不良的粗粒土渗透破坏坡降普遍要高的结论。为粗粒土的渗透稳定性与级配关系研究方向奠定了一定的基础,并指出了该研究领域的方向,为粗粒土的渗透稳定性工程特性做了有益探索。更多还原

【Abstract】 Through studying on the control experiment of the coarse-grained soil permeation damage slope of different grain composition,the paper points out that there is relativity between the scope of permeation damage and its grain composition of course-grained soil.And it comes to a conclusion that the permeation damage slope of the coarse-grained soil of well graded with a definite proportion of fine granule is higher than that of poorly graded.The study will lay a good foundation for the research on the relation between the permeation stability and the grain composition of coarse-grained soil.At the same time,the paper points out the direction of the research field,and provides some beneficial exploration for the engineering characteristics of the permeation stability of coarse-grained soil.更多还原
