| 1. | 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。 | | 2. | ( 2 ) validate whether the crest elevation can meet the require of energy dissipation and erosion prevention during the beginning period of flood discharge . ( 3 ) calculate the altitude of downriver cofferdam , and make it meet the require of energy dissipation and erosion prevention . ( 4 ) calculate some average velocity of flow through some sections , including contracted section in stilling basins behind upriver cofferdam , if the hydraulic jump happen in lower reaches of the river . the program will calculate the average velocity of flow of contracted section and the length of the apron
主要设计内容包括：计算上游围堰后消力池的尺寸；验证泄洪初期坝面高程是否能够满足消能防冲需要；计算下游围堰堰顶高程，使其满足泄洪期围堰和坝体过流的消能防冲和工程进度的需要；计算部分断面平均流速，包括：上游围堰后消力池中收缩断面的断面平均流速；坝首和坝末的断面平均流速；当下游河道发生水跃时，计算下游河道的收缩断面平均流速及需要铺设护坦的长度。 |
