| 摘 要： | 针对实际水利工程中深埋坝基砂层透镜体的液化可能性问题，用规范方法进行了初判和复判，并且根据室内动三轴试验结果用Seed法和Dobry法做了进一步的评判，对各种评判方法进行了综合性分析。根据分析结果，并结合实际工程条件，提出了无需专门对深埋坝基砂层透镜体进行处理的结论。

| Abstract: | Seismic liquefaction of deep-sand lens in a dam foundation is evaluated by two processes. Firstly, specification methods are used to make preliminary and again judgment. Secondly, Seed and Dobry methods are used with dynamic triaxial test results to make more evaluation. Various estimation methods are analyzed synthetically. Based on the analysis results and considering the practical engineering conditions, a conclusion that a special treatment is needn’t made for deep-sand lens in dam foundations, is drawn. |
