~~ 本文第一部分明确了在水电站设计工作中被长期混乱了的两种计算水头的意义。确切指出“水输机平均计算水头”H_r 和 H′_r,指出它既不等于 H_ρ,也不等于 H_α,而是当水轮机直径修正为标准值时与η=f(NH)图上水轮机限制出力缐转折点相应的水头。第二部分说明了增加(Q′1)min 和(Q′1)_α的影响。作者推导出设计水轮机时的最优单元流量(Q′01)_P=(2g~(1/2)πf((ηopδ)/(2)(tanα_esinα_e)/(cosβi))~(1/2)从而论证了修割叶片以增加单元流量的方法,同时总结了一系列增加单元流量的途径。并且指出增加单元流量对水轮机空蚀性能的影响。推导出能说明影响空蚀系数的普遍公式:σokp=(2ηor)/z((Q′01)_pH_p~(1/2))/(ωlf)+k~2+ηor-1这一公式也可以说明水轮机空蚀系数测定试验之所以要求在原始设计水头下进行的基本原因。第三部分是根据作者1957年2月份出席我国某大型水电站初步设计审查会议时所获得的资料。对某厂提出要求减少水轮机直径的各个方案进行了评述。并且指出选用 PC-211型水轮机的可能性。希望承制这顶水轮机的苏联列宁格勒斯... 文摘来源 The arch belly gravity dam is a new type of dam. Its upstream face is inclined and it has a belly arch within. The stress distribution of the dam section is comparatively uniform so that the strength of materials can be filly utilized; the vertical stress at the heel of the dam is comparative high so that the capability of the dam to sustain extraordinary overloading is high. .Comparing with ordinary gravity dam, its stress condition is greatly improved. In order to search for the best profile of new typ... 腹拱式重力坝是一种新坝型，坝上游面倾斜，坝内设有腹拱。坝体断面的应力分布比较均匀，坝体材料得到充分的利用，上游坝趾的垂直应力较高，坝体承受特殊超载的能力较大，比较一般砼重力坝的应力状态有了很大改善。为了寻找这种新坝型的最好轮廓剖面，利用偏光弹性力学的冻结应力方法，做了廿多组不同轮廓尺寸的坝体剖面的应力试验，经过平衡校核，对于推荐的剖面还进行了重复试验，认为试验结果是可信的。试验中个别方案还采用了软胶纲格法试验；并简化成无铰拱，用结构力学的方法进行了近似的应力计算。三种不同方法所得的应力情形是接近的。根据不同轮廓尺寸剖面应力试验的结果，分析了各种轮廓尺寸的变化对坝体应力分布的影响。初步认为确定坝体轮廓尺寸的规则如下：坝体上游边坡宜为：１∶０．２－１∶０．４，下游边坡宜为１∶０．７５－１∶０．９；腹拱宜做成略向上游倾斜的椭圆形；拱高宜为坝高的２５－３５％；上游腿应比下游腿略厚，以使重心偏向上游；设置坝内电厂时尾水管的宽度宜等于或小于坝段宽的３０％。最后推荐方案的应力试验成果，坝体基本上全部为压应力，坝体断面的应力分布均匀，上游坝趾的压应力较高。以１－Ⅷ号方案为例，坝内只个别点出... 文摘来源 This paper, based on the dynamic experiments in the laboratory simulation model, gives a theoretical analysis on loss-of-excitation protection for large hydroelectric generators.
