This will result in a change in the form and gradient of the channel. The direction of the displacement will lead to a reduction of the sediment carrying capacity of the channel, through which the river regains its equilibrium. The whole process is accomplished by the flattening of the bed slope, as suggested by the theories gene...             冲积河流上修建水库以后,下游河道将失去平衡。河流为了重新建立平衡,必将发生一系列的变化。本文对这—变化的过程,提出了一些新的概念。根据枢纽下游所在地区的地质地理条件,河流的坡降可以有各种不同的变化。坡降的渐趋和缓只是三种可能性中的一种,不能当做普遍规律来看待。河槽的重新建立平衡,主要是通过河床质的粗化作用。河床质的粗化现象具有两种不同的类型。一种是河床表层复盖物因清水冲刷而外移,露出了底下属于另一地质时代的较粗的卵石层,这时河床质的粒径会发生突变。另一种是由于水流的分迭作用,河床质的变化是连续的,徐缓的。在第二种情况下,河床质的粒径虽然变化不多,但是,通过河底沙垅的加多,却可以使曼宁糙率系数有很快的增加,这就使水流的流速降低,挟沙能力减小,河流逐渐建立起新的平衡。随着河床质的渐次粗化,河床的冲刷下切率与时俱減。野外实测结果及水槽试验成果都指出冲刷率与冲刷历时之间成一指数关系。河床质中不能为水流所挟运的颗粒所占百分比愈大,冲刷率下降得愈快,河道重新恢复平衡所需要的时间也愈短。从黄河下游的具体情况来判断,将来修建枢纽以后,下游河道在承受清水冲刷时可能作整体下降,坡降的变化不会很大。黄河下游的河床质虽然很细,同样也... 文摘来源          This paper is limited mainly to an analysis of the data presently available in the literaturc.Three topics have been investigated,namely, 1.the behavior of the resistance coefficient of an aerated flow, 2.the principal flow parameter for the correlation of data on air entrainment, and 3.the distribution of air concentration. According to Ehrenberger,the aerated flow in a channel consists of three zones of flow in addition to the zone of pure water that may possibly exist near the bed of the channel.These ar...             本文主要内容为根据前从资料探讨下列问题:1.掺气水流的阻力规律;2.控制掺气水流的基本参数;3.掺气浓度的断面分布。分析结果说明均匀掺气水流的阻力系数和底坡有着密切关系.这是清水水流所无的特异现象.已有资料的分析也说明 U/g~(1/2)是控制二元掺气水流的基本参数.在理论分析方面,我们提出了考虑质量脉动的概念,并提出了修改后的平均掺气分布微分方程式。 文摘来源          A systematic review on the gravitation theory of prof,M.A.Velikanoff has been made in this article in the following four respects:(1)the fundamental energy equation of the gravitation theory as well as the treatment of the so called “work of suspension”, which forms the nucleus of the theory,is incorrect;(2)the mathematical conclusion about the suspensions-carrying-ability of flows departs from the natural truth;(3)the formula deducted for the vertical distribution of silt-content contains mathematical erro...             本文对维里堪诺夫关于悬移质运动的重力理论作了系统的评述.论证了:维氏关于“悬浮功”的处理及浑水水流能量平衡基本方程式的建立所存在的问题;关于悬移质挟沙率(水流挟沙力)的数学结论偏离客观事实;关于悬移质含沙量沿铅垂线分布公式的推导过程不够严格,其结果与紊动扩散理论的公式具有类似的缺点.维氏对挟沙水流研究工作的贡献,文中也作了必要的肯定.在评述重力理论的同时,对悬移质运动过程及其特殊矛盾作了扼要的阐释,并附带介绍了作者近年来的有关研究结果. 文摘来源   << 更多相关文摘         相关查询: sediment handling sediment contamination sediment classification sediment analyzer serious sediment graded sediment sediment processes common sediment sediment profiles sediment modulus sediment computation terrace sediment  对查询结果不满意
