摘要：三峡库区大型涉水滑坡的工程治理效果，已经成为水库能否长期按要求正常运营的关键问题。在统计分析三峡库区二期、三期地质灾害防治工程特点的基础上，以库区巴东县15个典型已治理大型涉水滑坡为研究对象，汇总、分析了其工程防治方案，总结了大型涉水滑坡灾害防治工程措施以抗滑桩工程、护坡工程和排水工程为主的技术特点，并根据多次实际调查结果指出巴东县已治理大型涉水滑坡普遍存在的宏观变形间题。在此基础上，结合工程治理流程、现场调查结果，考患后期运营时可能发生变化的重要影响因素，采用层次分析法，建立了一个兼具时效性和预见性的多层次、多指标的综合评价体系，并基于综合评价值设定了评价标准，对工程治理效果进行分级。最后，以巴东县XLO1滑坡的工程治理效果评价为实例，检验此方法的实用性和有效性，并对巴东县典型已治理大型涉水滑坡的工程治理效果进行评价，结合实际调查结果，指出巴东县大型涉水滑坡工程治理效果良好，但仍存在一些问题。

Abstract: Engineering treatment effect of large-scale wading landslides in the Three Gorges Reservoir area has become a key issue that whether the reservoir can be in long-term normal operation. Taking the 15 large-scale wading landslides that have been treated in Badong County as the research object, this study summarized the large-scale wading landslides prevention and control engineering measures and analyzed the technical character-istics of large-scale wading landslide disaster prevention projects, and revealed that the anti-slide pile, slope protection engineering and drainage engineering have the highest utilization rate of engineering measures, and then pointed out the macro-deformation problems of engineering treatment based on the actual investigation. Combined with quantitative and qualitative evaluation method, this paper proposes an assessment approach with multi-levels and multi-factors. The index system was established according to the engineering treatment proces-ses, survey results and the important factors that might change in the late operation, And based on the compre-hensive evaluation value an evaluation standard was set up. The application case of XLO1 landslide shows that this approach is practical and effective. Finally, this paper classified the large-scale wading landslides engi-
