摘　　要：2005年主汛期,正在施工中的大隆水利枢纽分区土石坝遭遇了台风"达维"正面袭击,流域持续突降暴雨,入库最大洪峰流量在9 950 m3/s,坝前水位总涨幅达34.4 m,施工汛期土石坝度汛断面突发局部管涌现象,由于措施及时有效,土石坝经受住了百年一遇洪水的严峻考验,该文回顾管涌发生始末,探讨成因和措施,类似经验可供相关专业人员参考。In major flood season of 2005,the embankment dam in the subsection of Dalong Key Water Control Project under construction was directly attacked by the typhoon 'Dawei'. The rainstorm continuously fell in the drainage area. The maximum peak flood flow into reservoir is 9 950 m3/s. The mass rising water level in the front of dam was 34.4 m. The partial piping phenomenon burst out at the section of embankment dam in the flood season of construction. The embankment dam was successfully withstood with the ordeal of flood once in a hundred years because of the efficient measures in time. The article reviews the whole course of piping,and discusses the causes and measures. The similar experience can be referred for the relative technical members.
