新型级配图的分析与验证

Analyses and Verification about New Gradation Figure

通过马氏试验结果 ,验证了碎石矿质混合料级配最大密度时 ,实验指数为 0 .4 5的合理性 .同时对级配曲线半对数坐标、常数坐标、幂指数坐标三种形式的优缺点进行了详细分析 ,从理论上论述了幂指数坐标是级配曲线的最佳坐标形式 .最后用球体理论、干涉理论对实验指数为 0 .4 5时 。

This paper demonstrates the test index of crashed rock mix gradation when its density is maximum.Also,the advantages and disadvantages of semi-logarithm coordinate,constant logarithm coordinate and exponential coordinate are compared,and the exponential coordinate is proved as the optimal form of the gradation curve.Finally,according to sphere theory and interferential theory,the phenomena that the theoretical density is maximum when the test index is 0.45 is analyzed in detail.
