experimental study includes the law of flow field variation and variation of water surface in affected zone by the single groyne or twin-groyne.
实验研究包括单丁坝及双丁坝条件下丁坝影响区内流场及水面变化规律;
this paper studies on the law of the kinetic energy correction factor near a groyne by a flume experiment basing on one dimensional energy equation of steady flow.
本文从一维恒定流能量方程式出发,通过水槽实验,研究丁坝附近动能修正系数的变化规律。
a formula reflecting the stabilization of riprap in a closure work and of groyne head apron is thus deduced.
经过验算,沖深与抛石稳定性的计算与实际工程的结果较为一致。
