| Abstract: | 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. |
