笔者认为,在高浓度浑水的静水沉淀过程中,Kynch的将等浓度过程线当做直线并同时由筒底向上传播的理论是不完善的。笔者从淤积泥沙浓度是时间的函数的假设出发,论证了等浓度过程线为一曲线,且对不同浓度于不同时刻由筒底向上传播。笔者在Roberts关系式的基础上,推导出等浓度过程线、浓度分布曲线以及淤积层厚度变化曲线的理论公式。根据上述理论观点,提出了对Kynch理论的修正图解法。
The author believes that in the process of hydrostatic precipitation with high concentration of hydrophobic water, Kynch’s theory of treating the isoconcentration process line as a straight line and simultaneously propagating upward from the bottom of the cylinder is incomplete. From the assumption that sediment concentration is a function of time, the author demonstrated that the isoconcentration process line is a curve, and it propagates upward from the bottom of the cylinder at different concentrations at different times. Based on the Roberts relationship, the author deduces the theoretical formulas for iso-concentration process lines, concentration profiles, and thickness variation curves of sediments. Based on the above theoretical perspectives, a revised graphical approach to Kynch’s theory is proposed.
