| 中文摘要: |
| 介绍了速率过程理论及其相应的粘性土蠕变模型的推导，选取淮阴三类不同土质的粘性土样开展了蠕变试验研究，分别制备了各向异性和各向同性的结构试样，获得了相应的蠕变试验成果，最后用速率过程理论模型对试验成果进行了拟合。研究成果表明：以速率过程理论为基础而建立的蠕变模型能有效地模拟不同土质粘性土的蠕变过程、趋势和变形，反映出粘性土土性的本质特点，使土质学和土力学紧密地结合在了一起。 |
| 英文摘要: |
| The rate process theory and corresponding clayey creep model are introduced.The creep tests for 3 kinds of soils taken from Huaiyin area were carried out with anisotropic and isotropic structural soil specimens prepared separately.Finally,the corresponding test results were fitted using the clayey soil creep model.The results show that the creep model established on the basis of rate process theory can simulate the creep process,trend of development and deformation.It can reflect the essence characteristics of clayey soil.The model integrates the soil mechanics with engineering geology. |
