| 摘 要： | 对连续冲洗式沉沙池截沙率进行分析研究，并在一维流超饱和输沙法基础上，得出连续冲洗式沉沙池池段分组截沙率、工作段分组截沙率、大于某粒径级截沙率以及总截沙率的近似计算方法。为验证该方法的实用性，对连续冲洗式沉沙池的截沙率进行模型试验，试验结果表明：采用近似处理的截沙率计算公式，其计算结果与实测结果吻合较好，在符合计算精度的前提下，可以用于实际工程计算。

| Abstract: | Based on the supersaturated sand transfer method in one-dimensional flow, the approximate calculation methods for the sand interception rate in groups for the basin section and working section, the sand interception rate of grains with the diameter greater than a certain value, and the total sand interception rate were worked out. Model tests were performed on the sand interception rate of a continuous flushing sedimentation basin to verify the applicability of the presem methods. It is shown that the calculated result by the approximate calculation methods accords well with the measured data. Therefore, the approximate calculation methods can be used in practical projects. |
