摘要
黄土湿陷性系数的变化与其土体的其他物理力学性质存在一定的相关性,文中通过收集万家寨引黄工程北干线工程区原状黄土湿陷性土工试验及其物理力学试验资料,分析初探其抗剪强度在原状土状态与浸水饱和后变化值与湿陷性系数之间关系,通过线性回归分析初步得到其抗剪强度变化值与湿陷性系数之间的经验关系式。对于湿陷性黄土场地工程设计和重新评估湿陷性黄土浸水后对工程建设的危害提供一定的参考。
There is a certain correlation between variations of loess coefficient of collapsibility and other physical and mechanical properties of the soil.In this paper according to the collapsible soil test of the intact loess and the physical and mechanical test data of North Main Line Project area of Yellow River Diversion Project of Wanjiazhai,the relationship between coefficient of collapsibility and the change value of shear strength from undisturbed soil to immersion saturated soil was analyzed and the empirical relationship between the change value of shear strength,Δτ,and the coefficient of collapsibility was initially obtained through the linear regression analysis.Certain reference was provided to the engineering design of the collapsible loess site and reappraisal of the harm to the engineering construction of soaking of collapsible loess.
