| 摘 要： | 首先通过三轴蠕变试验获得了云母石英片岩的蠕变曲线,通过分析蠕变曲线,了解了云母石英片岩的三轴蠕变特性,然后利用线性元件组合模型的建模方法建立了云母石英片岩的黏弹塑性蠕变模型,并且拟合得到了该模型在径向和轴向的蠕变模型参数,最后将黏弹性蠕变模型理论曲线和试验曲线进行对比,两者在径向和轴向均吻合良好,说明所建立的黏弹塑性蠕变模型可以较好地描述云母石英片岩轴向蠕变和径向蠕变,验证了该黏弹塑性蠕变模型的正确合理性.该蠕变模型比西原模型多一个Kelvin元件,对衰减蠕变阶段的描述更加精确.

| Abstract: | Firstly,the creep curves of mica-quartzose schist are obtained through the triaxial creep test,its triaxial creep characteristics are found out by analyzing the creep curves,secondly,a viscoelastoplastic creep model of mica-quartzose schist is established by using the method of combined-component model,lastly,the creep model parameters are got by data fitting,the good consistency of the test curves and the fitted curves show the right and reasonable of the creep model.The viscoelastoplastic creep model esta... |
