摘　　要：　粘性泥沙特性研究中,水样、沙样和设备是至关重要的。作者经过大量试验表明,充分分散沙样使之成为原始单颗粒,在环形水槽中用同一电导的人工海水模拟现场不同流速、不同盐度、不同含沙量情况下粘性泥沙在水流中的起动、冲刷、落淤等,其效果十分优良。Water sample, sediment specimen and equipments are of most importance in the experimental study on the characteristics of the cohesive sediment. On the basis of a great deal of laboratory investigations, it is found that in order to obtain a sound effect, the sediment specimen should be dispersed into original particles, and then the characteristics of the cohesive sediment such as starting, scouring and depositing under different conditions of velocity, salinity and sediment concentration are modeled in the ring channel with the artifical sea water of the same conductance.
