摘要:
波浪作用下泥沙的起动和输移研究对航道回淤分析具有重要意义. 以往这类研究主要针对海岸地区的非粘性沙,而对于单纯波浪或以波浪为主要动力的粘性泥沙运动,特别是湖区底泥的研究相对较少. 本文通过波浪水槽试验对太湖底泥的起动和输移进行了研究,并提出波浪动力下含沙量经验公式,由此对太湖地区某具体工程的航道回淤进行分析计算. 该成果对研究波浪作用下淤泥的输移及太湖地区类似的航道回淤问题具有借鉴意义.

Abstract:
The study on the sediment transport due to waves is necessary for prediction of deposition of waterway. Owing to the lack of appropriate formula for calculation of suspended sediment load in Taihu Lake under wave action, an experimental study on transport of silt collected from Taihu Lake is conducted by using a wave flume. In this paper, the process of entrainment and suspension of silt is quantitatively described, and detailed measurements of suspended sediment profiles are carried out for each run of the experiments. Based on the test results, an empirical relationship for calculation of the mean suspended load on waves is presented. The verification results of a case study show that the present equation is satisfying to be used in prediction of sediment deposition of waterway in Taihu Lake.
Key words:  Silt in Taihu Lake  transport  deposition of waterway  wave
