1 前言广北水库位于胜利油田东营地区,位置在溢洪河与广利河以北的渤海莱洲湾退海滩涂荒碱地带,是一座以解决胜利油田和地方工业与生活用水、淡水养殖和部分农田灌溉而兴建的水库。但由于水库自身没有水源,提引黄河水是唯一选择。根据分析,黄河下游来水有以下特点:(1)来水来沙年际变化大,年内分布不均。(2)来水量逐年减少。(3)断流状况日益恶化。这些给引水工作带来了很多困难,因此,必须立足汛期抢水的观点。但高含沙量的水如果直接入库,势必造成水库库容迅速减小,缩短水库寿命。所以,建立一个与之配套的沉沙池非常必要。2 位置选定
1 Introduction Gubei Reservoir is located in the Dongying area of Shengli Oilfield. It is located in the Tuyao alkaline zone of Laizhou Bay in the Bohai Bay, north of the Spillway River and Guangli River. It is a key site for solving the problems of Shengli Oilfield and local industrial and domestic water, freshwater aquaculture and Some farmland irrigation and the construction of reservoirs. However, due to the fact that there is no water source in the reservoir itself, it is the only choice to promote the Yellow River water. According to the analysis, incoming water from the lower reaches of the Yellow River has the following characteristics: (1) There is a large interannual variation between incoming and outgoing water and sand and uneven distribution during the year. (2) The amount of water decreased year by year. (3) cut off the deteriorating situation. These have brought a lot of difficulties to the diversion work, therefore, we must base ourselves on the viewpoint of grabbing water in flood season. However, if the high sediment concentration of water directly into the reservoir, is bound to cause rapid reduction of reservoir capacity, shorten the reservoir life. Therefore, it is necessary to establish a matching desilting basin. 2 location selected
