文摘:综合阐述了珠江水利委员会科学研究所从1983 ? 1998年间对飞来峡水利枢纽的整体布置、施工导流、泄洪、通航、截流、闸孔断面形式、闸下消能形式、闸下冲刷等所进行的一系列试验和研究工作，并介绍主要试验研究成果。 - The reason to creates this kind of destruction to be very many , the main of them is that the apron partially has not been able fully to display it to eliminate energy affect so causes the ditch bed to wash out , forms flushes the pit , leading to the apron , to guard against flushes the trough and both banks slope protection destruction , for a long time , disappear power design of plunge basin and layout have been focused on disappear power . but not to give the enough value on uses the sea to inundate the section to disappear power and adjust speed to reduced downriver washes out
水闸闸下冲刷破坏的部位绝大多数发生在消力池下的海漫和防冲槽处,造成这种破坏的原因很多,其中很大一部分是由于海漫部分未能充分发挥其消能作用而引起渠床冲刷,形成冲坑,导致海漫、防冲槽及两岸护坡的破坏。一直以来,人们把消能的研究重点放在消力池的消能设计及平面布置上,而对海漫段消能及调整流速功能研究甚少,至于对海漫加糙水流运动建立数学模型,在国内外还很少见相关的论文资料。
