摘要
为验证考虑沙波阻力后能否有效提高水流挟沙力公式的计算精度,本文归纳了常用的床面总阻力系数的计算方法,提出了更为简洁的总阻力系数公式,并将该公式应用于一般形式的水流挟沙力公式,采用近岸实测数据进行验证分析。
In order to verify whether the calculation accuracy of sediment-carrying capacity formula can be effectively improved after taking sand wave resistance into account,the conventional calculation methods of total seabed surface resistance coefficient are summarized to produce more concise formula.The formula applies to the calculation of sediment-carrying capacity,which is analyzed with real measured inshore data.
