| 摘 要： | 通过对陕西洛惠渠五洞简易盾构法施工现场取样试验，在对试验Q1黄土的应力应变曲线特性进行分析的基础上，根据弹塑性理论提出了黄土的弹塑性软化本构模型，并将模型计算与试验结果进行比较。结果表明，该模型能够较好地模拟Q1黄土的软化和剪胀性。

| Abstract: | In this paper,the stress-strain and deformation behaviors of Q_1 loess of the fifth tunnel of Luohuiqu were analyzed by means of conventional tri-axial tests,on the basis of analysis of the stress-strain cure behaviors,the elasto-plastical model of Q_1 is proposed based on the elasto-plastical theory.Also,the comparison of model computation with testing curves is tested.The results indicate that the model can stimulate the softening and dilatancy behaviors of Q_1 loess. |
