摘要
缩尺效应是影响水工模型试验精度的重要因素之一。本文通过矩形薄壁堰试验 ,验证了缩尺效应的存在 ,分析了缩尺效应对矩形薄壁堰泄水能力的影响 ,推荐了计算精度较高的计算公式 ,提出了减小缩尺效应的措施及建议。
The scale effect is one of important factors of influencing hydraulic model test precision. By rectangle thin-plate weir test, this paper validates the existence of scale effect, analyses the affection of scale effect for discharging capacity of rectangle thin-plate weir, recommends a high-precision calculating formula, and puts forward the measure and the suggestion of reducing scale effect.
