摘　　要：针对阿克肖水库大坝基础能否直接或经过处理后坐落在湿陷性粉土深覆盖层上的问题进行分析研究,并对坝基的强力夯实、预先浸水、表层换填+强力夯实、全部挖除粉土等处理方案进行可行性分析,最终采取全部挖除粉土的方案。2018年11月下闸蓄水投入运行,经施工期、运行期监测,坝体沉降值在常规允许范围内,运行情况良好。The dam foundation in Akshor Reservoir Project is of deep layer collapsible silt, which should be treated appropriately.The feasibility of several different treatment schemes is analyzed, including dynamic compaction, pre-soaking, surface replacement with dynamic compaction, and complete removing of the collapsible silt.Based on the analysis results, the complete removing scheme is finally selected.After the treatment, the monitored dam settlement values during the construction period and the operation period since November 2018 are all within the allowable range.
