| 中文摘要: |
| 根据资料收集选取土石坝渗流量、渗透坡降等8个定量因素作为土石坝渗流风险评价的指标，使用粗糙集改进层次分析法组合赋权的方法获取各评价指标客观权重.建立组合赋权-TOPSIS评价方法，对6个土石坝进行渗流风险评价预测，获取土石坝渗流安全风险等级.与现场调查情况相比结果一致.研究表明：该方法对土石坝渗流风险评价准确便捷，可用于快速评价土石坝渗流风险等级. |
| 英文摘要: |
| According to the data collection，8 quantitative factors，such as seepage flow and seepage slope gradient，are selected as the indexes of seepage risk assessment of earth-rock dam，and the objective weights of each index are obtained by the combination of rough set and improved analytic hierarchy process.Combination weighting-TOPSIS evaluation method is established to evaluate and predict seepage risk of six earth-rock dams and obtain seepage safety risk grade of earth-rock dams.The result is consistent with the field investigation.The results show that the method is accurate and convenient for the risk assessment of earth-rock dam seepage，and can be used to evaluate quickly the seepage stability of earth-rock dam. |
