【摘要】 本文对甘肃巴谢河流域滑坡的分布和谷坡稳定性进行了详细的描述和分析。阐明了滑坡的分布特征及活动规律,并对谷坡稳定性进行了合理的分区。认为岩性、地形地貌和水文地质等条件是滑坡发育的主要控制因素。而重点考虑滑坡形成的坡体岩层结构条件以及滑动破坏的规模大小和滑动机制是滑坡的分类原则,得出了稳定性分区的条件是边坡的组成及岩性特征、地下水的作用、黄土层厚度和地形地貌等。更多还原

【Abstract】 This paper describes and analyses the landslide distribution and slope stability of Baxie river basin in Gansu province in detail. It expounds the landslides distribution characteristics and the active roles,and also reascrably classifies the slope stability regions. The rock characters, topographical, geomorphologicat and hydrological conditions etc. are considered to be the main control factors of landslide developing. The stratigraphic structure condition of landslide forming, the scale of sliding breaking and the sliding mechanism are the basic principles for landslides classification,and it is considered that the conditions of stability region classification are the formation of slope, the rock nature, the action of ground water,the thickness of loess stratigraphy, topography and geomorphology, etc.更多还原
