摘　　要：针对多粒径不规则骨料料层中复杂空隙的气流阻力问题,采用简化固定床流动模型,利用孔隙流(管道流)理论推导了单位长度料层气流阻力计算公式,并基于实测数据修正计算公式。结果表明,计算结果与前人实验研究数据相吻合,为类似工程应用提供了理论分析和准确计算的依据。With regard to the problem of various irregular size of the aggregate material layer flow resistance in complex air gap, the simplified fixed bed flow model is adopted and porous flow （pipe flow） theory is used to derive the per meter material layer resistance formula. According to the measured data, the formula is modified. It shows that the for- mula calculation results are consistent with the previous experimental data, which provides the theoretical analysis and accurate calculation basis for application of similar projects.
