摘要
基于非饱和土渗流和抗剪强度理论,分析了降雨条件下土体基质吸力对边坡稳定性的影响,探讨了考虑吸力和不考虑吸力条件下边坡的稳定安全系数,指出非饱和土坡稳定性与基质吸力有密切关系,基质吸力随含水量增大而减小,引起土体强度下降,土坡趋于不稳定。
Based on the unsaturated soil leakage a nd shearing strength, the paper analyzes the influence of the soil suction on the slope stability under the waterfall condition, explores the stability safety coefficient of the slopes with a nd without the suction, a nd points out the stability of the unsaturated slope has the close relationship with the matric suction and indicates the matric suction reduces along with the increasing water volume which can lead to the lower soil strength a nd the instability of the slope.
