摘　　要：地震堰塞湖/坝是4类堰塞湖/坝中破坏性最为严重的一种。2008年5月12日汶川8级强震造成具有一定规模的堰塞湖/坝共35座,其中极高危级的唐家山堰塞湖/坝成为当下世界关注的"悬湖"。简要介绍了唐家山堰塞湖的除险过程,并通过对我国1949年以来的地震情况及5.12汶川地震堰塞湖形成情况的分析,概述了对地震堰塞湖/坝先应急除险、后加固处理等综合技术。Earthquake-induced dammed lake/barrier bar which is formed by mountain-slope gliding in earthquake is the most destructive among the four sorts of barrier lakes/dams. Thirty-five barrier lakes/dams possessing a certain scale were caused and formed by the Wenchuan Earthquake of magnitude eight on May 12, 2008. A- mong these, the extremely dangerous Tangjiashan Quake Lake had become a hanging lake arising from the worlds attention. However, the risk was eliminated on June 11. This paper also makes a general introduction on the normal technology dealing with barrier lake/dam, which is to response the emergency event and remove the dangerous status before strengthening the barrier lake/dam.
