摘要: 露天礦運輸過程中,車速、路面粉塵負荷、粉塵含水率與揚塵濃度有密切的關系.通過對它們設計正交試驗和多元回歸統計分析,得到運輸揚塵質量濃度的計量模型,該模型具有99%的顯著性和擬合性.經回歸系數顯著性檢驗,自變量對因變量的影響均極為顯著,其顯著性大小依次為:車速、粉塵含水率和路面粉塵負荷.最后采用實測值與模型計算值的計算機擬合,對模型進行驗證.結果表明,該模型具有較高的可信度.

Abstract: Vehicle velocity, road dust load, and dust moisture have close relationships with dust mass concentration. Based on orthogonal experiment and multiple regression statistical analysis, a calculation model of dust mass concentration in traffic was established, with a significance of 99% and a better goodness of fit. The results of significance test of regression coefficients show that the effects of the independent variables on the dependent variable are very significant, with the order of vehicle velocity, road dust load and dust moisture. The agreement of the computed results with test data indicates that the model has high reliability.
