降雨要素对低渗透性土质边坡稳定性影响分析[EB/OL]
北京:中国科技论文在线
运用非饱和土抗剪强度理论研究了降雨要素对低渗透土质边坡稳定性的影响
在低渗透性土质边坡短期降雨情况下
考虑的降雨要素主要有降雨强度、降雨历时、降雨雨型和前期降雨与主期降雨之间的时间间隔
降雨强度的增大和降雨历时的增长均将使土坡稳定系数降低
type of rainfall
) Abstract: Based on saturated-unsaturated seepage theory, used the theory of shear strength of unsaturated soil, this paper studies the low permeability soil side slope on the effect of rainfall essential factor
Rainfall Intensity, rainfall duration, type of rainfall and the time interval between antecedent rainfall and main period of rainfall are the effects it considerated
With rain intensity and rainfall duration increased, the soil side slope stability factor is decreased; In the condition of short-term rainfall in the low permeability soil side slope,the same rainfall amount,and peaked type of rainfall,more times at the peak, the soil side slope stability factor is decreased
Keywords: soil side slope
