摘要
橡胶-砂混合土是由废旧橡胶轮胎经机械破碎得到的碎块或颗粒与砂土按一定比例配合而成的混合土。橡胶-砂混合土具有密度小、弹性变形能力强、模量低、阻尼大等特点,是一种优良、环保的新土工材料,可作为土木工程中的减隔震材料。为加快推进橡胶-砂混合土这一新土工材料在减隔震方面的工程应用,迫切需要对橡胶-砂混合土动力学相关理论与实践问题的研究给出解答。通过归纳和总结,阐述了橡胶-砂混合土动力学在动力学参数、动强度、动力特性经验模型3个方面的研究进展及成果,指出了现有研究成果的不足,并就未来的研究方向进行了展望,可为橡胶-砂混合土的工程应用及后续研究提供参考。
Rubber-sand mixed soil is a kind of mixed soil that is composed of fragments or particles obtained by mechanical crushing of waste rubber tires and sand in a certain proportion.Rubber-sand mixed soil has the characteristics of low density,strong elastic deformation ability,low modulus and large damping.It is an excellent and environmentally friendly new geotechnical material and can be used as a shock absorption material in civil engineering.To speed up the engineering application of rubber-sand mixed soil as a new geotechnical material in seismic reduction,it is urgent to study the theory and practice of rubber-sand mixed soil dynamics.Through induction and summary,the research progress and achievements of rubber-sand mixed soil dynamics in three aspects of dynamic parameters,dynamic strength and empirical model of dynamic characteristics are described.The shortcomings of the existing research results are pointed out,and the future research directions are prospected to provide a reference for the engineering application and follow-up research of rubber-sand mixed soil.
