| 摘 要： | 本文介绍了一种用力和位移的线性组合控制岩石试验的新方法。该方法已在一台自制的伺服实验系统上和一台MTS实验系统上得到了实现。用这种方法能够简便地求出通常难以求出的具有Ⅱ类特性岩石的全应力-应变曲线,而且能够变化出如广义应力松驰等其它实验类型,从而能够对时间依赖性进行深入的研究。由于其易于采用的特点,它在研究岩石破裂乃至摩擦等弱化过程方面有着广泛的应用前景。

| Abstract: | This paper introduces a new testing method developed by Okuboet el. which is used to control a linear combination of force and displacenlent. It was implemented on a specially designed servo-controlled testing system and a MTS machine successfully.The method may be used for many testing purposes concerning the mechanisms of weakening processes. Complete stress-strain curve can be obtained by this method and its application gives some testing methods such as generalized relaxation test, which may be used to investigate time-dependent failure behaviour ofrock. |
