摘　　要：为满足港口疏浚土处理需要,我国沿海部分港口建设了大型陆上临时纳泥区,但同时也对港口其他工程建设产生了一定影响。由于纳泥区具有临时性、占地范围大等特点,为保障港口建设发展,需对其进行改造、退让以满足其他工程建设需要。同时由于纳泥区存储大量新近吹填土,其安全稳定性是改造过程需要重点考虑的问题。本文结合工程实例详细阐述纳泥区围埝改造方案及工程实施后变形观测情况,以供其他类似工程参考。In order to meet the needs of dredging soil treatment,large temporary mud storage areas on land have been built in some coastal ports of China,but it also has a certain impact on the construction of other port projects.Since the mud storage area is temporary and covers a large area,it needs to be transformed and give way to meet the construction of other projects for guaranteeing the construction and development of the port.Due to the storage of a large amount of newly filled soil,the safety and stability are the key issues to be considered in the reconstruction process.The reconstruction scheme of cofferdam in mud storage area and its deformation observation after implementation are introduced through engineering examples,which can be used as a reference for other similar projects.
