通过数值模拟探讨了边坡土体的剪胀对边坡稳定的安全系数的影响,得出了剪胀性对边坡稳定具有积极的作用,且其影响程度与坡高及边坡土质材料有关的结论。同时,建议对于土质材料以粘土或粉质粘土为主的边坡,考虑剪胀角后的安全系数可增加0.03;而对于土质材料以粉土或砂土为主的边坡可增加0.02。
通過數值模擬探討瞭邊坡土體的剪脹對邊坡穩定的安全繫數的影響,得齣瞭剪脹性對邊坡穩定具有積極的作用,且其影響程度與坡高及邊坡土質材料有關的結論。同時,建議對于土質材料以粘土或粉質粘土為主的邊坡,攷慮剪脹角後的安全繫數可增加0.03;而對于土質材料以粉土或砂土為主的邊坡可增加0.02。

The influence of soil slope dilatancy angle on the slope stability is studied with numerical simulation .It come to a conclusion dilatancy angle has a positive effect on the slope stability w hich is determined by both the height and soil materials of the slope .We suggest the dilatancy angle safety factor can increase by 0 .03 if the slope soil materials is clay or sticky ,w hile for the sand or silt soil , the factor can be risen by 0 .02 .
