| 摘要: |
| 泥石流的活动特征及其危险性评价对电站的施工及运行有重要意义。根据羊湖电站厂房区勘查所获取的资料,对厂房区后山5条泥石流沟的成因进行了分析,在此基础上将层次分析法(AHP)应用到泥石流危险性评价研究中。对该厂房区5条泥石流沟的危险度评价表明,5号沟泥石流危险度最高,4号沟次之,1号沟、2号和3号沟危险度相对较低。泥石流危险度与流域面积的大小呈正比关系。 |

| Abstract: |
| The debris flow hazards are common in the construction of the hydropower stations.The method of the analytic hierarchy process proposed by Saaty is applied in this study to the risk assessment of the debris flow hazards in five debris flow gullies around No.2 Yanghu hydropower plant,Xizang.The results of assessment show that there is the most potential risk in the 5th debris flow gully,followed by the 4th debris flow gully.Particular attention and reasonable suggestions should be taken in the design and construction of No.2 Yanghu hydropower plant. |
