金沙江奔子栏库区达日开发区滑坡危险性评价

以金沙江奔子栏水源地工程为依托，采用组合赋权法和未确知测度理论建立滑坡危险性评价模型，选取奔子栏库区达日开发区滑坡进行危险性评价。以权的最小平方法确定评价指标的主观权重，熵值法确定其客观权重。评价结果表明:该滑坡危险性等级为中度，与现场调查结果相吻合。

Hazard Assessment on Landslide in Dari Development Zone in Benzilan Reservoir Area along Jinsha River

Relying on the project of Benzilan waterhead area along Jinsha River, combination weighting method and uncertainty measurement theory was used to establish landslide hazard assessment model which was then applied to the hazard assessment of landslide in Dari Development Zone in Benzilan reservoir area. The subjective weight of assessment index was specified by weighted least-square method, and the objective weight by entropy method. The result of assessment shows that, the risk grade of this landslide is medium, which is agreed by the field investigation.
