由于黄河的自然条件很独特,同时在三门峡水利枢纽中又需要采用一些新型结构,因此在初步设计阶段内就提出了不少的问题要求各科学研究要构及高等学校协助解决。根据问题的性质大体可分成三类:第一类是黄河流域特别突出的问题,例如三门峡水库的淤积和排沙;泥沙对三门峡水工建筑物的水平压力;懸浮泥沙对水轮机的磨损;由于人工措施进行水土保持后水量的减少;水库黄土岸坡的变迁;黄土地基的稳定性等。第二类问题是设计水利枢纽时必须研究的一般问题,主要是水工试验;混凝土骨料的选择;水
Due to the unique natural conditions of the Yellow River and the need to adopt some new structures in the Sanmenxia Hydro-junction, many problems have been raised in the preliminary design stage, which require that various scientific researches should be constructed to help colleges and universities to solve them. According to the nature of the problem can be roughly divided into three categories: the first is the Yellow River Basin particularly outstanding issues, such as Sanmenxia Reservoir siltation and sediment; sediment pressure on the Sanmenxia hydraulic structures; suspended sediment on turbine wear; The decrease of water quantity after soil and water conservation due to artificial measures; the change of bank loess slope; the stability of loess foundation. The second type of problem is the general problem that must be studied when designing a water conservancy hub, mainly the hydraulic test, the choice of concrete aggregate, the water
