Through a series of experiments on incipient motions after deposition and consolidation,the relationships between cohesive sediment incipient motion velocity and sediment dry density,cohesive sediment content under conditions of deposition and consolidation are studied,and conclusion that the cohesive .

通过粘性泥沙淤后起动试验,研究其起动流速与泥沙干容重、粘性颗粒含量之间变化关系,指出粘性泥沙起动流速随着泥沙干容重、粘性颗粒含量增大而增大,之后由试验数据率定出粘性泥沙起动流速经验公式,并用王兆印的试验资料进行了验证。
