| 摘 要： | 以皖南地区某强烈变形的强风化千枚质板岩边坡为例,通过对其工程地质条件的调查,结合边坡岩体结构类型和结构面组合特征,对其变形破坏特征及稳定性进行了分析和评价。研究结果表明,边坡的变形受坡内软弱岩体(挤压破碎带)控制,剪应力的集中易使坡体产生圆弧形滑动,据此定量评价边坡的稳定性,提出合理的支护方案,减小地质灾害发生的可能。

| Abstract: | Taking a strong deformed and weathered phyllite slate slope in the south of Anhui province as an example,through investigation into geology conditions and slope rock mass structure type,this paper analyzed and evaluated the slope deformation features and stability.The results indicated that the slope deformation was controlled by the soft rock mass(compressive rupture zone) in the slope,and the shear stress concentration can cause the slope to slide along circular-arc surface.The paper evaluated the slope s... |
