#K4pJm/b7U Pw0【中文摘要】 冲积性河流浅滩整治水位与整治线宽度是航道整治工程设计中的两个重要技术参数,是浅滩整治成败的关键。本文简要分析了浅滩形成的原因及影响浅滩演变的因素,回顾了国内外整治水位与整治线宽度研究进展。通过建立顺直微弯河段平面二维水流泥沙数学模型,在取得模型相似验证的基础上,对整治水位以及整治线宽度的各种组合所引起的航道冲刷过程进行了分析研究,分别探寻了整治水位、整治线宽度的变化对浅滩整治效果的影响,并从整治工程实施前后流场变化情况进行了初步分析。计算结果表明,整治线宽度一定时,整治水位越高,冲刷历时越长,浅滩冲刷幅度越大,随着整治水位的逐步抬高,整治水位的变化所引起的浅滩冲刷的变化幅度不大;整治水位一定时,整治线宽度越小,冲刷强度越大,浅滩冲刷幅度越大,随着整治线宽度的减小,浅滩冲刷的变化幅度越来越大。研究结果还表明,整治水位与整治线宽度是相互影响,相互制约的。随着整治水位的升高,整治线宽度变化对河床冲刷深度的影响愈来愈大;随着整治线宽度的减小,整治水位变化对河床冲刷深度的影响愈来愈大。并通过建立各种组合方案下整治工程前后断面宽度比与断面平均水深比关系曲线,得出适合所研究河段的整治线宽度计算公式。水利论文1x7~t0~#Jh7^

【英文摘要】 Regulation water level and regulation width of channel regulation engineering are two importants technical parameters in alluvial river, and the key to success of shoal regulation. This paper analyzes the reasons forming the shoal and the factors influencing the shoal evolution, and reviews the literature on the calculation methods of the two parameters in progress. The 2-D suspend mathematical model established in this paper is adopted in straight reach, on the basis of model similarity, a general research on the scouring processes of navigable channel caused by various regulation water levels and regulation widths has been carried out to find out the influence of two parameters to the scouring. And a preliminary analysis is given from the angle of the velocity changes before and after regulation project.The computed result indicates that, when regulation width certain, the regulation water level is higher, scour time lasted longer, the shoal scour depth is higher. Along with the regu...更多lation water level gradually run-up, the shoal scour change scope is not bigger; when regulation water level certain, the regulation width is higher, scour intensity is bigger, the shoal scour depth is higher. Along with the regulation width gradually reduction, the shoal scour change scope is bigger.The result also indicated that, the regulation water level and the regulation width affects mutually, restricts mutually. The regulation water level is higher, the effect on scour depth of riverbed because of the regulation width changed is bigger; The regulation width is smaller, the effect on scour depth of riverbed because of the regulation water level changed is bigger. And the relations between the rates of cross widths and cross average depths before and after the regulation projiects, the regulation width formula suiting the studies reach is obtained.  还原水利论文y)b0z H'wY
