【摘要】 试验所用黄土试样取自西安东郊十里铺,且试样均在同一探井4m深度处取得,属Ⅲ级自重湿陷性黄土,在室内分别用面积为30cm~2(小环刀)和50cm~2(大环刀)的环刀进行单、双线法湿陷性试验,同时用相同含水量的黄土试样在平行于黄土的沉积方向(纵向)和垂直于黄土沉积方向(横向)进行湿陷试验,最后得出了环刀面积和黄土的各向异性对其湿陷系数影响很大的结论。更多还原

【Abstract】 In this paper,the loess coefficient of collapsibility was tested by using circular knife of 30cm2 and 50cm2 in laboratory, then the difference of coefficient of collapsibility between vertical and lateral of loess was compared.Finally it was concluded that the area of circular knife and the anisotropy have great effect on the collapsibility of loess.更多还原
