摘要
以辽宁大伙房输水隧洞出口河段为研究对象,基于实测资料,利用平面二维水流泥沙数学模型,计算了大伙房输水隧洞出口河段内水流和泥沙冲淤的分布形态,预测了出口河段30年内的水沙运动趋势,为工程实践提供了参考。
Taking the river section near the outlet of LiaoNing DaHuoFang tunnel as research object,and based on measured data,this paper simulated the velocity field and the sediment transportation in the research river section,and predicted the water and sediment transportation trend in 30 years.The results could be a reference for the engineering practice.
