| 摘 要： | 建筑垃圾土的变形机理复杂，它不同于传统意义上的土体。通过大量的非线性有限元计算，找到了双屈服面模型中影响建筑垃圾填埋场沉降的主要参数，并给出了各参数与沉降之间的定性关系，为建筑垃圾填埋场沉降计算和参数灵敏度分析奠定了基础。 |
| 关 键 词： | 建筑垃圾 沉降 双屈服面模型 灵敏度分析 |

| Abstract: | The deformation mechanism of construction waste is complicated and is differ from the traditional soil. By a lot of nonlinear finite element method calculation, the main parameters, which have much larger influence on the calculated accuracy of construction waste landfill settlement, are found out; and then the qualitative relations between every parameter and settlement are also given; and the results can be the basis of settlement calculation and parameters sensitivity analysis of construction waste landfill. |
| Keywords: | construction waste settlement double yield surface model sensitivity analysis |
