摘　　要：电厂取水口建掩护堤后，取水口、取水渠等处的回淤必须在电厂建设之前予以解决。基于实测资料，分析了广东第三核电站沙环站址海区的波浪场、潮流场及水体含沙量场，并结合电站的取水布置特点，对取水渠及其它有关水域回淤进行了分析计算，预测了不同区位的回淤强度。分析表明，取水口取水并不会引起取水渠回淤增加。If there exists shelter embankment at the water intake area of a power plant, the back silting at the place of intake and intake canal etc. must be solved before the construction of the power plant. Based on field data, the wave field, tidal current field and sand concentraction at the sea area of Shahuan site of the third nuclear power plant of Gangdong province, were analyzed. Combined with the characteristics of the layout of water intake canal and its related water area were carried out. The results expressed that the water inlet will not result in increasing the back silting of intake canal.
