In the sub-cluster scale theory, R1 indicated the possibility which the hole skip the middle size hole to become a big cell, it would make striking influence on the tensibility ; R2·R1 indicated the well-distribution degree of cell size, it would make the notable influence on the cell density P; R2/R1 indicated the big cell and small cell exchange possibility, it would make the remarkable influence on the re-spring degree because of the different influence with the hole size.
其中R1表征泡孔越过中等泡向大泡孔缔合的倾向,它对断裂伸长率影响最大;R1·R2表征泡孔的均匀性,受泡孔密度影响较大;lnR2/R1表征体系在发泡过程中大小泡孔相互转化倾向比,由于大小泡孔对泡体回弹率贡献不同,lnR2/R1对发泡体回弹率影响较大。

The result notes that dynamic triaxial test preferably simulate the actual stress state of grading macadam, and Uzan model which considers the shear performance of material can better reflect stress states of grading macadam. Regression coefficients of the model obviously present nonlinear characteristic with moisture changed, and to further influence dynamic resilient module.More the module is larger, more diminishing rate of maximum tensile stress on pavement Bottom is smaller. To enhance draining function and strength, the gradation should been rigid controlled, and which the content of less than 0.075mm is controlled between 5~7% and spring-back is controlled between200~300MPa are appropriate.
结果表明,动三轴试验较好地模拟了级配碎石层的实际受力状态;Uzan模型考虑了材料的剪切性能,更能反映了级配碎石在隧道路面中应力状态;随含水量的变化,Uzan模型中回归系数变化呈明显的非线性特征,进而显著影响级配碎石的动态回弹模量的变化;级配碎石模量越大,路面层底的最大拉应力减小率越小;为了兼顾到级配碎石层的排水渗透功能和强度,应严格控制级配,特别是0.075mm以下的含量宜控制在5%~7%,级配碎石的回弹模量宜控制在200~300MPa之间。
