葛洲坝大江截流工程,经过近十年的设计和试验研究,已于1980年10月下旬戗堤下河进占,1981年元月4日胜利合龙。为配合各阶段设计和施工,曾在1/106整体模型、1/60截流模型、1/80局部模型(后改为1/60)和1/60断面模型上进行过导、截流水力学的反复试验研究,积累了大量的资料;在实际截流施工中,又进行了相应的原型观测,为指导施 Gezhouba Dam River closure project, after nearly 10 years of design and experimental study, has been in late October 1980 under the embankment into the river, January 4, 1981 won the victory. To cope with the design and construction of each stage, we have carried out the guidance and closure of hydrodynamics on the 1/106 overall model, the 1/60 closure model, the 1/80 partial model (later changed to 1/60) and the 1/60 section model Repeated experimental research, accumulated a large amount of information; in the actual closure construction, but also carried out the corresponding prototype observation,
