摘　　要：依据电厂取水口附近海岸线变化及海域水深测量数据 ,采用水下实测地形比较方法 ,分析电厂营运初期取水口附近海域冲淤变化 ,结果显示 :海域淤积速度远远大于自然沉积环境下的淤积速度。进一步分析认为海岸线外移、码头及取水管等工程构筑物对海域流态影响、泥沙来源量增多、护岸滑坡及 9914号强台风等因素是导致淤积加快的主要原因 ,并讨论了该海域减淤的若干措施。Based on the variations of coastline and water depth,using the method of sea floor digital model,analysed in this paper is the submarine scouring silting variance in the area around the intake of Songyu Power Plant at initial operation stage.It is proved that the silting rate now is much higher than the rate in nature.Further research is done.It is shown that many factors,such as the coastline moving seaward, the ocean current affected by docks and intake pipe structures, the sediment sources which increase obviously, the shore landslide and the effect of typhoon No.9914,have been playing the main role in the fast silting.Some measures are discussed for reducing the silting in the area.
