摘要

利用美国15个实验室模型、土耳其6个模型和1个原型的实测数据，计算了不同闸门开启和湖面高程下弧形闸门泄水道的流量系数。22个溢洪道的C值与《小型水坝设计》图9-31中给出的C值的比较没有显示出密切的一致性。可以确定，C取决于角度和比值d/H1，而不是仅在d和H1为闸门开度和上游水头的情况下才取决于角度，并且对每个大坝单独计算具有统计意义的回归方程。

Discharge Coefficients for Radial-Gated Ogee Spillways by Laboratory Data and by Design of Small Dams

Using the measured data on 15 laboratory models in USA, six models and one prototype in Turkey, the discharge coefficients ( C ’s) of radial-gated ogee spillways for various gate opennings and lake water surface elevations are computed. Comparison of these C ’s for 22 spillways with the ones given by Figure 9-31 of Design of Small Dams does not show close agreements. It is determined that C depends on both the angle Ɵ and the ratio d/H 1 , rather than Ɵ only where d and H 1 are the gate opening and the upstream head, and statistically significant regression equations are computed individually for each dam.

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
