舟曲县瓜咱坝1号滑坡是中层中型的错落转化型破碎岩石老滑坡。通过地质调绘及现场勘查对该滑坡的工程地质条件以及滑坡的基本特征进行了研究。指出了引起滑坡变形破坏的主要影响因素是滑坡区的地质构造、地层条件、气象因素和人类活动的影响。总结了老滑坡的变形破坏及复活模式为老滑坡-前级不连续崩塌-坡体卸荷、松弛变形-牵引后级滑坡滑动-后级拉裂、滑移-推动挤压前级滑坡-整个滑坡的复活，为滑坡稳定性分析及工程治理提供了依据。

The landslide that took place in the No. 1 Guazan dam in Zhouqu county is identified as an old landslide caused by dislocated broken rocks and medium-sized masses. The incident itself features medium scale and can be categorised into the transformed type. The paper,by the means of geological mapping and in-situ investigation,conducts in-depth research on the geological conditions of the project and the general features of the landslide. The results point out the major causes of the incident-the geological formation and the stratum of this area,the meteorological conditions,as well as human activities. At the same time,the deformation damage and its renewal model are concluded as follows:old landslide-discontinuous collapse of the front layers-unloading behaviour of the slope; relaxation deformation-cause of the slide in the rear layers-splitting of the rear layers under pulling force;slide-slide in the front layera under pushing force-renewal of the slope. Hopefully,the paper can be of value for the stability analysis of the landslide and project treatments.
