Abstract

在区域地质灾害(滑坡、泥石流)风险区划的基础上,可以采用概率分析方法对区内风险防御工程治理的效益进行评价。该方法首先是对区内防御工程按等级分类,建立工程类型等级标准;然后可根据区内工程类型等级分别评价防御工程的抗风险能力和风险损失折减概率;最后按3级标准划分风险损失折减的效益。作者应用该方法对汶川大地震极震灾区的都江堰白沙河小流域地质灾害防御工程,进行了风险损失折减概率效益评价,并得到了有推广价值的结果。

Other Abstract

The probability method was adopted to evaluate disaster preventing engineering benefit based on the regional hazards risk assessment. The method classified engineering grades firstly and determined the standard of classification. And then,according to the grade of different engineering type,the ability to resist risks of engineering and risk reduction loss probability were evaluated separately. Finally,the benefit of risk reduction loss was classified into 3 grades. The method has been used to evaluate the risk reduction loss probability of preventing engineering in Baishahe watershed of DuJiangyan city of Wenchuan Earthquake disturbance area and the result was good and worth to be popularized.
