| 摘 要： | 本文着重研究圆柱形平底压模的底座尺寸对岩石应力状态的影响,研究结果表明,当底座尺寸增加时,岩石破坏形式从整体剪切破坏变为局部剪切破坏,然后变为冲剪破坏。在此基础上,对岩石承载的稳定性问题也作了简要讨论,图7,参4。

| Abstract: | The paper mainly deals with the influence of base dinensions of mould cylinder flat base, on stress conditions of the rock. The results show that with the increas ing of the base dimensions, the failure type of the rock mass will change from the integral shearing failure to partial shearing failure, then the punching shearing failure. Stability of the rock bearing was also briefly discassed. 7figs., 4refs. |
