中文摘要：

在页岩坚韧和它的机械参数之间的关系具有为基于地球物理的记载数据在大深度预言页岩坚韧的意义。大量实验为厚墙的柱体的人工的页岩标本的坚韧测量被执行，与使用的内部压力。而且，有限元素方法被用来解释坚韧。标本的声学的速度被测量，在页岩坚韧和机械参数之间的关系，几乎线性，被建立。

英文摘要：

The relationship between shale toughness and its mechanical parameters is of significance for predicting the shale toughness at a great depth based on the geophysical logging data. A large amount of experiments is performed for toughness measurement of the artificial shale specimens of thick-wall cylinder, with internal pressures applied. Moreover, the finite element method is used to interpret the toughness. The acoustic speeds of the specimens are measured and the relationships between shale toughness and the mechanical parameters, which are almost linear, are established.
