在对贝雷法的原理分析的基础上,并依据不同公称粒径,对贝雷计算方法提出了改进,引入了“虚拟筛孔”的概念、并针对不同的公称粒径,提出了相对合理的控制参数。在进行混合料优化设计时,可用贝雷法对级配进行筛选,以尽量保证混合料形成嵌锁结构。 Based on the principle analysis of Bereth and based on different nominal particle sizes, the calculation method of Berets is proposed and the concept of “virtual sieve” is introduced. According to the different nominal particle sizes, Relatively reasonable control parameters. In the process of optimizing the mixture design, the grading can be sieved by Bereau, so as to ensure that the mixture forms an embedded lock structure.
