轮胎–土复合结构体力学性能的研究

The Research on Mechanical Properties of Tire-Soil Composite

摘要: 近年来，随着大量废旧轮胎的产生，而又没有适当的方式来处理废旧轮胎，对于这种现状，本文提出了一种新型复合材料结构—轮胎土复合结构体，针对该结构单体的力学性能及组合体的抗剪强度进行了室内试验及数值模拟研究。得到的结果如下：1) 轮胎对内部土体具有约束作用，可以显著提高土体的抗压性能；2) 推求出轮胎–土复合体的粘聚力和内摩擦角；3) 数值模拟出轮胎–土复合体支挡结构水平位置变化量。本研究为废旧轮胎的回收利用提供了新的途径，同时为复合结构单体和组合体在实际工程中的应用提供了理论支撑。

Abstract: In recent years, with the production of a large number of waste tires, and without the proper way to deal with the waste tire, for this kind of situation, this paper proposes a new type of composite material structure—tire-soil composite, in view of the structure of the monomer combination of mechanical properties and shear strength for the study of indoor experiment and numerical simulation. Results are as follows: 1) the tires for internal soil have a constraint function, and can significantly improve the compressive properties of soil; 2) the cohesive force and internal friction angle of the tire-soil complexes are calculated; 3) the horizontal position variation is conducted through the numerical simulation of the tire-soil composite’s retaining structure. This study provides a new way for waste tire recycling, and at the same time provides a theoretical support for composite structure monomers and combination in the practical engineering application.
