摘要:
对废旧轮胎颗粒–砂混合物进行水平循环剪切试验,研究竖向荷载、轮胎颗粒含量以及轮胎颗粒尺寸3种因素对混合物的等效动剪切模量和等效阻尼比的影响.结果表明:竖向荷载越大,轮胎颗粒与砂混合物的动弹模量越大,等效阻尼比越小;轮胎颗粒含量增加,混合物的等效动剪切模量与等效阻尼比并不是都呈单调变化;试验中,在相同条件下,小粒径的轮胎颗粒与砂混合物的动弹模量相对要小，等效阻尼比要大一些.上述的试验结果给废旧轮胎颗粒–砂混合物在工程应用提供一定的参考.
Abstract:
This paper uses the mixture to study its dynamic shear modulus and equivalent damping ratio underthe different vertical loads and different tire particles content through horizontal cyclic simple shear test.Theresults show that when the vertical load on the mixture between waste tire particles and sand increases， its dy-namic shear modulus increases and its equivalent damping ratio decreases. The dynamic shear modulus and e-quivalent damping ratio of mixture is not a monotonous variation with the addition of tire particles content. Inthe test，the dynamic elastic modulus of the mixture between tire particles in small size and sand is relativelysmall and its equivalent damping ratio is relatively big，which can provide a reference in engineer applicationsfor the mixture between waste tire particles and sand.
