摘要
通过列举合川段锁坝整治实例,分析了锁坝在该段汊流滩整治中,除堵塞支汊抬高主汊水位外,还兼有如“增加水流输沙能力”“顺坝”“丁坝”等其他一些整治作用。故在选择锁坝位置时应兼顾发挥这些作用,以更好地提高锁坝的整治效果。
Taking the closure dam at Hechuan reach of Jialingjiang River as an exam-ple, it is seen that the action of closure dam will not only close up the flow of bifurcated channel, but also raise the water Ievel of main channel and increase the ability of silt transport. Moreover, it will act as 'training dike' or 'spur dike' as well as the other regulating struotures. For this reason, we must take these actions into consideration when selecting the position of closure dam, 餺 as to make the efficiancy of regulation work promoted.
