摘　　要：以风电场区探井中所取的180组原状样的室内试验成果为依据,分析该场区黄土天然含水量、孔隙比、干密度、湿陷系数在垂向上的变化规律及黄土孔隙比、干密度等物理性质指标与湿陷系数的关系,探讨利用黄土物理性质指标进行湿陷性评价方法的可行性,对黄土的湿陷性评价及地基处理方案的优化设计具有重要的意义。In the paper, the change laws in vertical of water content, void ratio, dry density and collapsibility coefficient of loess are analyzed, as well as the relationship between the coefficient of collapsibility and several indexes of physical property, such as void ratio, dry density, etc. , on the basis of the laboratory experiment results of 180 groups of undisturbed samples taken from the exploratory pits in the wind power ground. And then, the authors discussed the feasibility of evaluating the collapsibility through the physical property of loess. The conclusion is of important significance for the evaluation of loess collapsibility and the optimization design of the foundation treatment scheme.
