Distorted river model, designed according to Froude's Law, generally requires a rather high value of Manning's roughness n. Artificial roughness of such high magnitude is difficult to obtain in the model. The use of small gravels or coarse sand to adjust the required roughness will reduce the effective cross-sectional area and raise the water surface elevation in the model.

Distorted river model, designed according to Froude's Law, generally requires a rather high value of Manning's roughness n. Artificial roughness of such high magnitude is difficult to obtain in the model. The use of small gravels or coarse sand to adjust the required roughness will reduce the effective cross-sectional area and raise the water surface elevation in the model. It is very difficult to estimate the effect due to such a reduction of cross-sectional area. River model designed not according to Froude's Law is suggested in this paper. Model roughness is selected arbitrarily, and other hydraulic elements are proportioned according to Manning's formula. It is proved that, even though the Froude Number in the model is many times larger than that in the prototype, the deviation of model water surface elevation from prototype is generally negligible, and moreover, such deviation may be corrected by using specific energy curves.

按照夫劳特定律設計的变态河工模型,一般地要求在模型中有相当大的滿宁粗糙系数n。在模型中要得到那样大的人造粗糙系数是有困难的,用小石塊或粗沙来得到所要求的糙度,將会減少有效过水断面面积,並且抬高模型中的水面高程。由於过水断面面积的減少而引起的影响,是难於估計的。在本文中,介紹了不按照夫劳特定律設計的河工模型。模型的糙度是任选的;其他的水力要素,根据滿宁公式按此例求得。試驗証明,在模型中的夫劳特数,虽然大於原型的夫劳特数很多倍,根据模型試驗获得的水面高程与原型水面高程的誤差,一般是可以忽略不計的,同时,这种誤差可以用單位能量曲線予以校正。

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.The experimental results check the derived equations basically.Some empirical equations have been prepared to facilitate the application of experimental data.The discharge coefficients of free overflow of 27 different profiles of 16 practical spillways obtained by model tests have also been collected to verify the curvature effect equatiohs given by this paper Their practical agreement is also acquired.

本文根据劳弗尔(H.Lauffer)氏在两项假定[(1)垂直测线上各点所含能量为常数,(2)流线呈同心圆弧]下所导得的基本公式,作了详细的补充引伸,得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组,试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式,应用时可更简便。此外,也曾搜集了16个实用溢流壩包括27种断面曲线形式的流量系数模型试验资料,来验证流量系数所受的曲率影响,基本上也相符合。

本文中介紹了某些有关於涵管式小型進水閘的試驗成果,及藉量綱分析法而推導出来的水力計算公式。並对于實驗结果進行了討論,对水力計算公式中的某些系数進行了物理解釋。与干渠中心綫相正交的涵管式小型進水閘,是渠系中所广泛采用的分水建筑物的一种形式。但是,有关的水力計算,尤其是在分流情况下的水力計算問題,也和在其他水流情况下的分流問題一样,在已有文献中刊載得還是很少的。在1956年度,我教研室進行了一項有关此问题的委托試驗,今就該項工作中所得到的涵管式小型進水閘的水力计算問題的某些結果和討論介紹于此。
