Hongjiadu hydraulic power plant is the only leading water storage reservoir of wujiang cascade hydraulic stations , which is a full - time storage reservoir . 2 * landslide body is distributed at the right side of downstream , which is just located in the region of energy dissipation . erosion gully may cut the bottom of the landslide body . there are roads on the top of the landslide body during the construction period and operating period 洪家渡水电站是乌江梯级水电站中唯一具有多年调节性能的“龙头”水库， 2 #塌滑体分布于坝址下游右岸，恰好位于泄洪消能防冲区内，冲坑将塌滑体下部切脚，而且施工期和运行期在其上都布置有公路，因此2 #塌滑体失稳将影响整个水电站的正常运行。
In this paper a date from some real projects are used to analyse the facors that will affect the energy dissipation and erosion prevention . such as flood discharge across the cofferdam , crest elevation , downriver cofferdam , roughness coefficient and the gradient of the surface of dam , and so on . in this paper , the program based on hydraulics is checkout by the tankeng waterpower project in zhejiang . the results prove that this program can be used to design any project where there is no obvious side shrinking phenomena 本文结合工程实际对影响围堰和坝体消能防冲的各种因素，包括过堰流量、坝面高程、下游围堰堰顶高程、坝面糙率、坝面坡度等进行了分析，并借助水力学知识和计算机语言编写了围堰和坝体的优化计算程序，并利用浙江滩坑水电站工程对所提出优化计算程序进行了验证，证明了该程序在没有明显的侧收缩的影响下，计算结果与实际情况较为吻合。
And if the scour is too serious , it will be difficult to protect main project from destroy and cause economical loss . therefore to dissipate the unwanted energy and to make the cofferdam and dam can move safe against scour caused by flow is one of conmmon problems faced by this kind of hydraulic engineers 但是，由于围堰过流通常都会对围堰和坝体造成冲刷，严重的冲刷会使主体工程受到破坏，造成经济损失。因此，如何进行围堰和坝体的消能防冲，使围堰和坝体能够安全过流就成为此类工程中的一个重点问题。

Based on experimental result of energy dissipation and scour protection for downstream of spillway at yu jian kou power station , this paper discusses the flow characteristics , aerated characteristics of flaring gate pier for low dam pivot , the influence on pressure of dam surface and the result of energy dissipation for flaring gate pier . it is put forward to be an available method to solve the problems of energy dissipation and scour protection for depth of covering strata , poor geologic condition and weakness of resistance to scour capability under reasonable use of flaring gate piers and auxiliary dissipaters . thus , a new method is obtained for release of floodwater and energy dissipation of low dam pivot which are provided with low water head , great unit discharge and low froud coefficient . it may be used for reference for design and test workers 结合鱼剑口电站坝下消能防冲试验研究成果，对低坝枢纽宽尾墩的水流特点、掺气特性、宽尾墩对大坝泄流能力和坝面压力的影响以及宽尾墩的消能效果等问题进行了初步探讨，提出了合理地使用宽尾墩结合辅助消能设施可有效地解决坝下覆盖层深，地质条件差，抗冲能力弱的低坝枢纽的消能防冲问题，从而为具有低水头，大单宽流量，低佛氏数特点的低坝枢纽泄洪消能开辟了一条新途径，可供有关低坝枢纽设计与试验工作者借鉴与参考
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。
