摘　　要：针对《公路工程集料试验规程》(JTGE42—2005)中细集料筛分试验存在的不足,通过大量试验研究,采用统计方法分析影响筛分试验结果的各种因素,提出了减小试验操作误差的试验控制标准和增加摇筛时间的方法。试验结果表明,提出的解决措施可以有效降低细度模数试验值的离散性,减小试验操作规定不完善性带来的误差。In light of the shortcomings existing in the fine aggregate sieving experiment in Test Methods of Aggregate for Highuay Engineering(JTG E422005),through extensive experimental research,statistical methods were used to analyze various factors that affect the results of screening experiments,and experimental control standards were proposed to reduce experimental operation errors and methods to increase shaking time were proposed.The experimental results indicate that the proposed solutions can effectively reduce the discreteness of the fineness modulus test values and reduce the errors caused by incomplete experimental operation regulations.
