| 摘 要： | 在陕西洛惠渠五洞简易盾构法施工现场进行了取样，分析了Q1黄土的应力—应变曲线特性及物理性状，根据连续损伤力学和热力学定律，提出了Q1黄土的弹塑性损伤本构模型。并将模型计算结果与试验曲线进行了比较，模型验证结果表明，该模型能够较好模拟Q1黄土的软化和剪胀性。

| Abstract: | In this paper the stress-strain and deformation characteristics of Q1loess of the 5th tunnel of Luohuiqu canal were researched by means of conventional tri-axial tests. And the elastoplastic damage model of Q1loess is proposed based on the continuous damage mechanics and the law of thermodynamics. Compared the experiment curves with the computation result of this model, it is shown that the model can stimulate the softening and dilatancy characteristics of Q1loess. |
