摘要

在黄河口潮滩和室内环形土槽模拟新沉积的海床土体，观测固结过程中沉积物临界起动切应力的变化及对应的土体重度、含水率、贯入阻力、剪切强度指标值的变化，分析黄河三角洲粉质类土临界起动切应力的影响因素与变化规律。研究发现：黄河三角洲粉土的临界起动切应力与重度、贯入阻力和抗剪强度之间呈正相关关系，而与含水率呈负相关关系，并且与干密度、抗剪强度之间具有非常好的定量关系。将黄河三角洲粉土临界侵蚀切应力的试验结果与其他学者建立的计算公式进行了比较，发现在固结开始试验与计算结果间的吻合性较好，随着固结时间差异性变大，表现出黄河口粉质土的独特性。

Abstract

During the consolidation process of new deposited seabed which had been simulated both on tidal flat of the Yellow River Estuary and in a circular soil bin indoors

the critical shear stress and physico-mechanical properties

such as bulk density

water content

penetration resistance

shear strength

were measured to analyze the influencing factors and variation of the critical shear stress of silty sediment in the Yellow River delta. Research shows that there is a positive correlation between critical shear stress and bulk density

penetration resistance

shear strength; while negative correlation between critical shear stress and water content and good quantitative relationship between critical shear stress and dry density

shear strength. Comparing test results with ones calculated with formulae in references

the individualism of critical shear stress of silty sediment in the Yellow River delta is obtained.
