| 摘 要： | 文中通过分析软岩流变特征找出流变速度与作用载荷之间的关系。利用U-相关曲线确定能够反映流变过程的4个特征点(流变起始点、等速流变起始点、加速流变起始点、流变破坏点).根据4个特征点的变化规律确定临界等速流变应力的方法和流变强度取值原则。

| Abstract: | The rheological characteristics of incompetent rock are analysed by using U-t curves for the whole process of rheological deformation. The relationship between the rheological deformation rate p and stress a is given. The characteristic stress point of their rheological process is found on -d chart. The author proposes an approach to determine rheological stress of the crtical uniform rate rheololgical stress with ji-ij the inflection point of a curve and the principle of determining rheological strength is decribed. |
