【摘要】：为了防治卜尔色太沟孔兑泥沙入黄危害,通过对该孔兑水沙特性及治理工程现状进行分析,提出在库布齐沙漠腹地配套建设东、西两个滞洪区蓄洪滞沙,总库容分别为1 357万、1 262万m~3。工程建成运行后,在发生2003年典型洪水的情况下,次洪分水比为0.196,分沙比为0.225,可有效减少孔兑入黄泥沙。根据孔兑工程建设和沿岸群众的治沙用洪经验,总结出孔兑治理思路为"拦、分、滞",主要措施为在上游修建拦沙堰或拦泥库,清浑分治、旁侧分沙,运用有利地形蓄洪滞沙。
[Abstract]:In order to prevent and control the harm of sand and sediment in Boersetaogou, through the analysis of the characteristics of water and sediment and the present situation of the project, the paper puts forward the construction of flood and sand storage and retention in the east and west of two flood detention areas in the hinterland of Kubuqi desert. The total storage capacity was 13.57 million ~ 12.62 m ~ (-1) ~ (32) m ~ (-1). After the completion and operation of the project, in the case of typical flood in 2003, the ratio of secondary flood and sediment is 0.196 and 0.225 respectively, which can effectively reduce the yellow sediment. According to the construction of Kongdui project and the flood control experience of the coastal masses, the author concludes that the main measures are "blocking, dividing, and holding". The main measures are to build the sand barrier Weir or silt reservoir in the upper reaches, clear the muddy part, divide the sand on the side, and use the favorable terrain to store the flood and the sand.
