The study results show that the weaken degree of strongly disturbed zone is 60% and that of weakly disturbed zone is 30%.

研究成果表明，强、弱卸荷区岩体性状弱化程度分别为60%和30%左右。

Some stabilizing structures must be set before cutting a bedding high rock slope, and how to determinate the range of disturbed zone becomes the key problem.

开挖顺层岩石高边坡，往往需要进行预加固，因而合理确定坡体开挖松动区范围就便成为核心问题。

The interpretation of the observed data indicates that: (1) the rock mass in the slope deformed mainly in a shallow belt underneath the excavation surface, termed as disturbed zone.

成果分析表明：（1）边垃岩体的变形具有明显的分区性，主要变形区被定义为边垃岩体松动区；
