强度应力比 [qiáng dù yìng lì bǐ]
strength-stress ratio
- HC分类提出了考虑高地应力和岩爆烈度的地应力折减系数，而取消了强度应力比S；
For HC classification method, considering the influence of high primary stress and rock-burst, propose primary stress reduction factor K, cancel the index of ratio of strength and stress S. - 由于矿柱破坏发生失稳的现象是一种突变现象，属突变理论研究的范畴，建立计算矿柱应力强度比的尖点突变模型，实现对矿柱失稳的预测。
Fourthly, the cusp catastrophe model is built to forecast the instability of the mine pillar for the damage of the mine pillar belongs to the study category of cusp catastrophe. - 对隧道围岩计算得出各类岩体强度应力比均大于6，该隧道围岩能够承受围岩应力的作用，不会产生过大的整体塑性变形、剪切及弯折等变形破坏。
The ratios of all rock strength stress are more than 6, so that plastic, shear and flexure deformations would be seldom happened under the stresses.
