摘要
以2010年9月19日新疆阿合奇县牙尔巴西沟泥石流为例,通过现场勘查和室内计算,分析了该泥石流特征并对其形成机理进行了研究。针对该区域的泥石流物源特征和下游沟道淤积的特点,提出了"拦挡+停淤"的治理方案,主要包括修建拦砂坝和停淤场等防护措施。研究结果可为新疆南麓区域泥石流的分析与防治提供参考。
Taking the debris flow of Ya＇erbaxi gully in Akqi County, Xinjiang Region on 19th, September, 2010 as an example, the characteristics of the debris flow is analyzed and the formation mechanism is studied by field survey and indoor calculation. The harnessing plan of retaining plus silting and consolidation is put forward aiming at the features of the debris flow source in this area and silting characteristics in the downstream gully. The major measures includes the construction of sand - sediment dam and silting and consolidation field etc.. The results can provide reference for the analysis and prevention of the debris flow in mountainous area of southern Xinjiang region.
