摘要
分析泥沙干容重及水下休止角的影响因素,并且从极限浓度和干容重的关系出发,推导出干容重的计算公式.运用散体沙的楔入堆积模型,推导散体沙的水下休止角计算公式,并结合干容重计算公式,计算散体沙的水下休止角.验证分析表明,公式计算结果与实测资料基本一致.
The influencing factors of dry density and the angle of repose are emphatically analyzed; and from the correlation between slurry limit concentration and the angle of repose, a calculation formula of dry density is deduced. And by using the wedge accumulation model, a formula for calculating the angle of repose of symmetrical dispersed sediment is deduced; and then combining the calculation formula of dry density, the angle of repose of symmetrical dispersed sediment can be calculated. Validating analysis shows that the result of the formula is in accord with field data.
