【摘要】 涡管排沙措施以前主要是解决推移质泥沙问题。本文通过对悬移质涡管排沙的近似分析，建立了悬移质涡管排沙分流比与截沙率之间的关系，并指出了其适用范围，从而将涡管排沙技术由解决推移质问题扩展到解决悬移质泥沙问题，试验基本上验证了理论分析结果。为了提高悬移质涡管排沙效果，文中还建议了几项技术措施。更多还原

【Abstract】 ilt discharge through scrolls was previously used to deal with bed load.In this paper.approximate of suspended load discharge is used to establish a relationship between the silt-discharge divergent stream percentage and the silt detention ratio. Also,the scope of application of this measure is defined therein to cover not only bed load but also suspended load.The tests have practically verified the theoretical analysis.In order to make this measure more effective,some technological schemes are proposed in this paper.更多还原
