摘　　要：兰州皋兰山Ⅰ-4号滑坡紧靠市区,严重威胁滑坡前缘的人民生产、生活安全,对其进行稳定性分析和防治具有重要的现实意义。滑坡区年内降水集中,暴雨强度大,山坡陡峻,水流侵蚀强烈,岩土体工程地质性质较差,新构造运动强烈,水文地质条件对滑坡极为不利。在人为因素诱导下,滑坡出现明显的复活特征,滑坡在暴雨和地震两种工况下稳定性较差。结合滑坡特征和地形地貌条件,建议采用桩板式抗滑挡土墙对滑坡进行治理。The paper studied the factors such as precipitous hillside, rainfall, water flow erosion, nature of rock and soil, geologic structures and hydrogeological condition which influenced the stability I 4 landslide of Gaolanshan in Lanzhou. Recent research show that the landslide body appeared obvious creep deformation which was induced by manmade factors, the landslide would be unstable under heavy rainfall and earthquake. According to the geographic and geomorphic conditions and landslide feature, the treatment of pile-plank retaining wall is suggested for landslide control.
