摘　　要：摘要：武汉东湖通道湖底淤泥工程主要处理东湖通道围堰区域内的东湖湖底表层淤泥。工程设计首先确定了本工程处理后的淤泥消纳单位和处理后的淤泥泥质及尾水标准，然后在综合分析各种淤泥处理方法的基础上，结合本项目的实际，确定对围堰1～3区和围堰4～5区的淤泥分别采用压滤脱水固结法和原位固结法进行处理，并介绍了这两种淤泥处理方法的工艺流程、主要构筑物及配套设备。实际处理效果表明其达到了设计要求且淤泥总量大幅减少。This project is to treat the surface sediment of the bottom in the cofferdam area of the East Lake channel. The disposal plant of the treated sediment in this project and the standards of treated sediment and tail water were determined. Based on the comparative study on the characteristics of the different sediment treatment methods, and according to the situation of this project, it was determined that the pressure dehydration consolidation method and the in situ consolidation method were used for the treatment of the sediments in the cofferdam areas 1 to 3 and 4 to 5 respectively. The process flow, main structures and auxiliary equipment in these two methods were introduced. The actual treatment effect showed that the design requirements were achieved, and the total volume of sediment was greatly reduced.
