摘要
黄土地区的边坡失稳与雨水入渗有密切关系.利用边界条件的转换来模拟雨水入渗,用差分法分析了降雨强度、降雨持时和土体的渗透系数与边坡稳定性的关系.通过对这些参数的数值分析研究,得出的结论可为边坡的失稳预防提供理论依据.
There is a close relationship between slope destroy in loess areas and rainfall infiltration.The rainfall infiltration is simulated by using the transition of boundary conditions,and the relationship of rainfall intensity, rainfall durative time, factor of infiltration and slope stability are analyzed in difference way. These parameters are studied numerically in order to enumerate the conclusions and provide theoretic basis for slope destroy prevention.
