摘　　要：通过对土围堰施工、钢围堰施工和水下施工 3种方案的对比分析 ,确定黄沙港闸反拱底板修补加固采用水下施工技术 .介绍底板裂缝的修补材料。The underwater construction techniques are adopted to mend and reinforce the inverted arched bottom plate of the Huangshagang sluice on the basis of comparison and analysis of the construction methods of soil cofferdam and steel plate cofferdam, and underwater construction. The materials for mending crevices in the bottom plate and underwater construction techniques are introduced. The underwater construction techniques for reinforcement of the inverted arched bottom plates of sluices with specially shaped thin reinforced concrete are developed for sediment laden rivers.
