| 摘 要： | 结合某水电站地下厂房工程实例，通过现场地质调查，分析厂房区挤压性围岩大变形破坏机理，定性的阐述强度应力比与围岩变形状态对应关系。参考类似隧道的经验把这一关系数量化，在此基础上，对水电围岩分类HC法的强度应力比降级进行修正，并运用它对地下厂房的软岩大变形程度进行预测。

| Abstract: | Based on a practical project of the underground powerhouse in a hydropower station, me cssennal deformation and destruction characteristics of squeezing ground were analyzed according to on - site investigation in geological features, and the stress intensity ratio and the corresponding relationship between the ground deforma- tion were described qualitatively. Reference to the experience of similar tunnels to quantify this relationship, On the basis, for water and electricity intensity of rock classification HC Act to amend stress ratio degradation, and use it to predict the large deformation of soft - rock of the underground powerhouse. |
