中文摘要：

利用GDS多功能三轴仪对K0固结的垃圾土样进行了七条应力路径的三轴试验,探讨了不同应力路径下垃圾土的应力-应变关系,给出了q-εs、p′-εv、p′-εs和q-εv的关系曲线。结果表明：垃圾土偏应力随剪应变几乎呈线性增加,表现出明显的加工硬化特征。同等剪应变的情况下,当Δp为正Δq也为正时,应力比（η=Δq/Δp）较大的应力路径对应的偏应力较小;当Δp为负Δq为正时,应力比较大的应力路径则表现出较高的抗剪强度。偏应力q不仅与剪应变有关同时也与体应变有关,球应力p不仅与体应变有关还与剪应变有关,填埋方式对垃圾体的应力和应变分布有重要影响。

英文摘要：

In order to explore the mechanical properties of the solid waste under different stress states,by using the GDS standard triaxial stress path testing system,the drained shear tests were conducted for the anisotropically consolidated solid waste at seven different stress paths,the stress-strain relationship in different stress paths were discussed,and the relation curves between q-εs、p′-εv、p′-εs and q-εv were given.The results show that the deviatoric stress of the solid waste is increased almost linearly with the shear strain,showing the obvious work hardening characteristics.Under the condition of equivalent shear strain,when Δp and Δq are all positive,the stress path with the larger value of stress ratio（η=Δq/Δp） shows the lower deviatoric stress;when Δp is negative but Δq is positive,the stress path with the larger value of stress ratio shows the higher strength stress.The deviatoric stress q is not only related to the shear strain,but also related to the volume strain;the spheric stress p is not only related to the volume strain,but also related to the shear strain.All these as mentioned above show that the landfill method is a key factor influencing the distribution of the stress and strain of solid waste.
