摘　　要：高坝洲水电站二期工程截流是在清江上游隔河岩水电站停机控泄下和利用一期完建的底孔作导流的特殊条件下进行的，从而形成了龙口（ 宽３０ｍ） 小流量（１３０ ｍ ３／ｓ） ，大落差（２６１ ｍ ） ，高流速（５２ｍ／ｓ） 的特点与国内类似工程相比，难度相对较大，由于精心设计和科学组织施工，截流取得了圆满成功，为高坝洲第１ 台机组比计划提前４The second stage closure of Gaobazhou project proceeded under the special conditions, that stopping operating and taking use of the bottom tunnel to divert, there fore the second stage closure can form a flow of 136m 3/s, a fall of 2 61m and a high-velocity of 5 2m/s at the scite of closure mouth Compared with other domestic similar projects, the second stage closure has relatively more difficulties Through precise design and scientific construction, the second stage closure has achieved a complete success It saves valuable constraction time about 4 months, therefore the unit NO 1 can generate electricity at an earlier date in comparison with the planning
