水坠坝或称泥浆自流式冲填坝,是利用水力将筑坝土料冲拌成一定浓度的泥浆,自流到筑有围埂的坝面,经脱水固结而成的土坝。七十年代初期,我国陕、晋地区劳动人民总结了前人引水拉沙淤地造田的经验,创造了这种筑坝方法。迄今为止,据不完全统计,我国已建成水坠坝8164座,其中坝高在15米以上的有5385座,坝高大于30米的有13座, Water slump dam or self-flow mud embankment dam, is the use of hydraulic mud will be mixed into a certain concentration of soil mud, gravity flow to the built dam surface, the dehydration and consolidation of earth dam. In the early 1970s, the working people in the Shaanxi and Jin region summed up the experience of water-logging in the Laashe silt land by the past and created this method of damming. So far, according to incomplete statistics, 8,164 water drop crashes have been built in our country, of which 5,385 are dam height above 15 meters and 13 are above 30 meters high.
