| 1 | 综合蒸发法和冷镜露点法测量水-土特征曲线和非饱和渗透系数(英文)显示文摘目的:综合使用HYPROP和WP4C两种仪器,探索采用蒸发法和冷镜露点法测量大吸力范围的水-土特征曲线,并采用收缩曲线对土体变形进行修正。方法:1.采用HYPROP仪器,在0~100 kPa吸力范围内测量土体的水-土特征曲线。2.当吸力大于600 kPa时,采用WP4C仪器,测量土体的水-土特征曲线。3.采用传统张力仪吸力板仪器,在0~500k Pa吸力范围内测量土体的水-土特征曲线。4.采用Satyanaga et al.(2017)公式,对实验数据进行拟合。5.采用HYPROP仪器直接测量土体的非饱和渗透系数。6.采用蒸发法,获取干缩曲线。结论:1.采用Satyanaga et al.(2017)公式,对实验数据进行拟合,拟合参数直接关联到进气值、拐点及方差。拟合结果显示,不同仪器所收集的水-土特征曲线的数据相互吻合,为水-土特征曲线的实验测量提供了更大的吸力范围。2.采用HYPROP仪器测量的非饱和渗透系数和采用传统改装的非饱和三轴实验数据基本吻合,因此,HYPROP可以作为在低吸力范围内(<100 kPa)测量非饱和渗透系数的有效仪器。3.当进气值小于100 kPa或者大于500 kPa时,综合采用HYPROP和WP4C可以有效缩短实验周期。 | Alfrendo SATYANAGA Harianto RAHARDJO Zhe Hao KOH Haneena MOHAMED | 2019 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2019，0，5： | 4 |

| 11 | Characteristics of unsaturated soil slope covered with capillary barrier system and deep-rooted grass under different rainfall patterns Check for updates显示文摘Rainfall-induced slope failures commonly occur in residual soil slopes.Slope failures are triggered by the reduction in soil strength.This is attributed to the decrease in soil suction due to rainwater infiltration.Slope covers like capillary barrier system and vegetative cover are effective methods that can be used to prevent rainfall-induced slope failures.The capillary barrier system is able to limit the rainwater infiltration,and vegetation can contribute to the increase in soil strength.Vetiver grass is widely planted in tropical and subtropical areas of the world for soil and water conservation.This study investigates the characteristics of unsaturated soil slope covered with capillary barrier system and Vetiver grass in comparison with the original slope through numerical analyses and field measurements.The analyses were carried out under the advanced,normal,and delayed rainfall patterns.The results of the analyses indicated that the capillary barrier system played a more significant role than the Vetiver grass in maintaining slope stability,although both the capillary barrier system and Vetiver grass contributed to the slope stability.In addition,both numerical analyses and field measurements showed that under the delayed and normal rainfall patterns,when antecedent rainwater infiltration could increase the soil moisture,the capillary barrier system performed much better compared to Vetiver grass in maintaining soil matric suctions and slope stability. | Yangyang Li Alfrendo Satyanaga Harianto Rahardjo | 2021 | International Soil and Water Conservation Research2021，9，3： | 1 |
