摘要:
各类海洋工程如码头、航道、海上风电、海底管道管线、填海造陆、防波堤等涉及的抛石、爆破、疏浚、打桩、开沟、吹填溢流等作业环节产生的悬浮物，在水动力作用下输移、扩散，会引起周边海域悬浮泥沙浓度增加，对海洋生态环境产生不利影响。文章对国内施工悬浮泥沙浓度扩散规律研究方法和数值模型中悬浮泥沙源强的选取方法进行了综述，为海洋工程施工过程产生的悬浮泥沙扩散研究提供参考和依据。

Abstract:
There is an increasing attention focusing on ocean engineering related to environmental and ecological problems such as blasting, pipeline laying, dredging, dumping of dredged materials, rock dumping, and blow filling, among others, which will lead to the suspension of sediments and increase of the concentration of suspended sediments in the surrounding sea area. In this paper, the methods to measure the concentration diffusion of suspended sediment in domestic constrution and the methods to select the source strength of suspended sediment in numerical models are summarized, which provide reference and basis for the study of suspended sediment diffusion in the process of marine engineering construction.
