摘要： 废旧轮胎回收利用于岩土工程回填领域取得了一系列理论和试验成果。根据国内外大量文献，综述了利用废旧轮胎改良砂土、膨胀土、黄土、黏土的研究进展。总结了不同掺量、不同粒径的轮胎在改良不同土质过程中的作用机理和效果。文献表明：粒径较大轮胎块的掺入在剪切面之间发挥了其本身固有的特性，增加了混合体的抗剪强度，而橡胶颗粒掺入土中是通过改善接触面上的摩擦特性增强土的剪切强度。轮胎与不同土体混合作为轻质土工材料用于岩土工程和路基工程，能够很好地改善土体强度、弹性性能、压缩性能。有关废旧轮胎在改良不同土的抗剪强度过程中的疲劳性、老化性和其对环境的影响仍需要进一步研究。

Abstract: Both theoretical and practical progresses aspects of the application of recycled tires in the geotechnical engineering have been achieved in recent years. This paper presents a state of the art review of the application of shredded waste tire chips in the strengthening of various soils, such as, sandy soils, expansive soils; collapsible loess and cohesive soils. The results and effects of various mixing contents and tire chips sizes in these soils are reviewed. The results indicate that, larger tire chip size can improve the frictional resistance at the face of shearing and therefore increase the strength of mixed soils. The tire chips mixed soils can reduce the unit weight in the geotechnical and roadway engineering and can improved both strength and stiffness of soils. It is suggested that the cyclic shear resistance, aging effect of tire chips and impact of tie chips to the adjacent environment need to be further investigated.
