摘　　要：在野外现场渗水试验和室内实验的基础上,探讨了黄土湿陷性与湿度的关系,提出了黄土广义湿陷系数和潜在湿陷系数等新概念,定量分析了这些参数与湿度的关系。据此,作者认为黄土可以不是一次完成浸水湿陷,具多级湿陷特性。The relationship between loess collapsibility and humidity is studied by field spot tests and experiments . New concepts,such as extend collapse coefficient and potential collapse coefficient, are put forward. More over, quantitative analysis on relationship between these parameters and humidity is done. Here by, the authors conclude that loess collapsibility has character of multilevel.
