在实体模型试验的基础上，对官厅水库的泥沙淤积发展和妫水河口拦门沙的清淤疏浚措施进行了研究。为了最大限度地减小疏浚挖槽的回淤量，必须依靠控制上游来沙量、调整入水口门位置、加设防淤堤及提高库水位等手段，而不能通过调整挖泥槽宽度、位置及数量等措施来达到目的。为此，在比较各种疏浚方案效果的情况下，提出了挖泥槽与增设折线型防淤堤相结合的清淤疏浚措施。
Based on the solid model test, the development of sediment deposition in Guanting Reservoir and the dredging dredging measures at the estuarine and lagoon of the sluice are studied. In order to minimize the amount of silt dredged dredging must rely on the control of sediment flow to adjust the position of the water inlet door, the addition of anti-dike and improve the reservoir water level and other means, but not by adjusting the ditch width, location and Quantity and other measures to achieve the goal. Therefore, under the condition of comparing the effect of various dredging programs, a dredging dredging method combining the dredging trough and the additional polyline-type anti-sloughing embankment is proposed.
