摘　　要：通过对甘肃省陇南市甘家沟进行实地调查,从地质地貌、水文气象和物源特征三个方面分析了泥石流的形成条件,总结了甘家沟形成区、流通区及堆积区的发育特征.以此为基础,分析计算了甘家沟泥石流的动力学特征参数(泥石流容重、流速、一次过流总量、整体冲击力、最大冲高和爬升高度),并得到了泥石流的危险范围.结合甘家沟泥石流形成条件及发育特点,提出了工程治理与生态保护相结合的综合治理方案,可为类似工程提供参考.Based on the field investigation of Ganjiagou in Longnan City, Gansu Province, the formation conditions of debris flow were analyzed from three aspects: geological and geomorphological features, hydrometeorology and provenance characteristics. The developmental characteristics of the formation zone, circulation zone and accumulation zone of Ganjiagou were summarized. On this basis, the characteristic parameters of debris flow in Ganjiagou(debris flow capacity, flow rate, total overcurrent, overall impact, maximum height and climb height) were analyzed and calculated, and the hazard range of the debris flow was obtained. According to the characteristics of the formation and development of the debris flow in Ganjiagou, a comprehensive treatment plan combining engineering treatment and ecological protection was proposed, which can provide a reference for similar projects.
