    摘要:

    通过现场勘察、应用改进Mein-Larson降雨入渗模型、数值模拟和理论分析等技术手段,分析了降雨型黄土滑坡稳定性和形成机理,研究结果表明:随着降雨强度和历时的增加,在坡脚处形成暂态饱和区,导致坡体应力场和位移范围发生变化,表层土体抗剪强度降低,推断出该滑坡为蠕滑-拉裂型滑坡。

    Abstract:

    Through on-site investigation, application of improved Mein Larson rainfall infiltration model, numerical simulation and theoretical analysis, the stability and formation mechanism of rainfall induced loess landslides were analyzed. The research results showed that with the increase of rainfall intensity and duration, a transient saturation zone is formed at the foot of the slope, leading to changes in the stress field and displacement range of the slope, and a decrease in the shear strength of the surface soil. It is inferred that the landslide is a creep tensile crack type landslide.
