摘要
在现场地质勘察的基础上,分析了毛尔盖水电站烧发河支流牙窝沟泥石流的成因,描述了泥石流沟的特征,运用工程地质分析方法对泥石流沟形成条件进行了定性分析,计算了不同概率下泥石流的峰值流量及总量,对牙窝沟泥石流发展趋势及影响范围进行了预测分析,并在此基础上提出了相应了防治措施。
Based on field geological prospecting, the genesis of debris flow at Yawogou Valley along Shaofahe River beside Maoergai Hydropower Station is analyzed and the characteristics of this debris flow valley are depicted. Then the paper carried out qualitative analysis against the forming conditions with the rationale of engineering geology; at the same time, the peak flow and total volume of the debris flow under different probabilities is calculated and its developing trend and affecting range are predicted. On this basis, the corresponding prevention measures are proposed.
