| 中文摘要: |
| 指出目前广泛应用的膨胀岩一维膨胀本构关系Huder-Amberg模型的缺点，通过试验研究，得到了修正的膨胀岩一维膨胀本构关系。在此基础上，研究了岩石浸水条件下应变随时间的变化规律，并将时间效应引入膨胀本构模型，得到了膨胀岩一维非稳定膨胀的本构关系。最后基于金尼克条件将一维本构模型拓展到三维。 |
| 英文摘要: |
| The widely used Huder-Amberg model for describing 1-D swelling constitutive relationship of rock is proved to be unsatisfied in some aspects. Based on the swelling test a revised 1-D swelling constitutive model is proposed. The law of swelling strain changing with time after the rock infiltrated with water is experimentally studied. With the time introduced into the swelling constitutive relationship, the 1-D transient swelling relation of swelling rock is developed and the 3-D constitutive relationship model is established based on the assumption that the swelling strain is caused by the first invariant function of stress tensor and the axial stress of Huder-Amberg uniaxial dilatancy test is agree with A•H•Jinike equation. |
