| 摘 要： | 铁板沙是汉江库区变动回水区的一种泥沙淤积现象,是沙浪、沙垄运动的产物.根据实测资料分析,得出了铁板沙的形成必须同时满足的两个条件,一是粒径在0.1～0.5mm的中细沙占80%以上;二是床面流速需大于2.0m/s.为进一步研究铁板沙的形成与治理提供参考.

| Abstract: | Consolidated sand, caused by the movement of sand wave and longitudinal dune, is a silting phenomenon takes place in backflow zone of Hanjiang Reservoir. According to the data from on-the-spot survey, to form the consolidated sand two conditions that 80 percent of sand diameter must between 0.1mm and 0.5 mm and that the speed of top river must be above 2.0m/s have to be met at the same time. |
