摘　　要：首先指出在淤积固结条件下粘性细泥沙具有与非粘性泥沙不同的起动冲刷过程和现象,并对粘性细泥沙起动冲刷机理和影响因素进行了分析,最后对粘性细泥沙起动冲刷计算的研究成果进行了系统总结,分析了各类计算公式的特点,提出了进一步需要解决的问题。This paper first describe the different phenomena and process of incipient motion and scour between cohesive fine sediment and non-cohesive sediment, and then analyzes the mechanisms of incipient motion and scour and the main effect factors, which are important to compacted cohesive fine sediment. Finally some formulas to calculate the incipient motion and scour of compacted cohesive fine sediment are systematically summarized, and their advantages, disadvantages and limitations are analyzed. In addition, further study is suggested.
