摘　　要：黄土滑坡已成为影响黄土地区公路、铁路等基础设施建设的主要因素,滑坡的形成在一定程度上就是滑带土变形破坏过程。从黄土滑坡滑带土的分类、物理力学性质、宏观与微观特征等方面进行了较系统的研究,探究其变形和破坏规律。结合甘肃天水的黄土滑坡实例进行了具体分析。Loess landslide is the main factor which influences the infrastructure construction such as highway, railway and so on. In certain extent, the formation of the loess landslide is the deformation and destruction of sliding soil. The paper made a systemic study including the classification, physical and mechanical properties, the microcosmic and macroscopic properties of the sliding soil. And the deformation and destruction of sliding soil mechanism are explored. At last, the loess landslide case of Tianshui, Gansu Province was analysed.
