摘要
三峡水库变动回水区上洛碛河段在三峡蓄水运用后,出现了泥沙回淤问题,对航道条件造成一定影响。本文根据实测资料,分析了上洛碛河段的卵石沙波群运动规律,研究表明:上洛碛河段的卵石沙波波长为40~60 m,波高变化约0.8~1.6 m。结合物理模型试验研究,提出了航道整治方案。试验结果表明,整治方案可有效改善上洛碛河段的通航条件,航道整治效果良好。
After the operation of Three Gorges Reservoir,there has been a problem of sediment siltation in Shangluoqi reach in the fluctuating backwater area of Three Gorges Reservoir,which has a certain impact on the channel conditions.Based on the measured data,this paper analyzes the movement law of the pebble sand wave group in Shangluoqi reach.It is found that the length of the pebble sand wave in Shangluoqi reach is 40-60 m,and the wave height changes about 0.8-1.6 m.According to the physical model experiment,the channel regulation scheme is proposed.The regulation results show that this scheme can effectively improve the navigation conditions of Shangluoqi reach,and the channel regulation effect is excellent.
