根据悬移质输沙率测验测定断面平均含沙量符合部分流量加权法的原理，推算出利用垂线相应的流量权重系数与垂线的平均含沙量直接计算出断面平均含沙量的公式。这种利用取样垂线间部分流量权重法计算断面含沙量的方法，解决了悬移质输沙率测验和流量测验不同步的问题。通过实例验证了利用流量权重法推求断面平均含沙量的方法，各项误差指标都达到规范精度要求。

Calculating mean sediment concentration in section by measuring suspended sediment discharge con-forms to partial flow weighted method. According to this principle,a formula is derived for directly calculating the mean sediment concentration in section with the flow weighted factor and the mean sediment concentration corre-sponding to the vertical. This method is a solution for suspended sediment discharge measurement not in synchro-nous with flow measuring. The results of test demonstrate that each error index conforms to accuracy requirement of specifications when applying flow weighted method to calculate mean sediment concentration in section.
