【 摘 要 】

In this research, an indoor standard compression test of waste tire particles reinforced lime-ash soil is conducted to study the compressibility of the reinforced soil as a foundational material in collapsible loess areas with large thickness. And during this process, the void ratio and compression coefficient of the soil samples with different ages and blending amounts are tested. The research results can be concluded as: (1) The compressibility of waste tire particle reinforced lime-ash soil is better than that of lime soil and plain soil, and thus it can be widely used in large-thickness collapsible loess areas. (2) In all the waste tire particle reinforced lime-ash soil samples, the sample with the blending amount of 30% is superior to the other. Therefore, in making waste tire particle reinforced lime-ash soil, it is suggested to apply the soil with reasonable mix ratio of 30%.
