摘要

摘要: 以某拟建水电工程近坝库岸的岩石高边坡变形体为典型实例 ,结合现场勘察 ,对岩石高边坡时效变形的地质表现进行了观察分析 ,从宏观和微观上揭示了岩体时效变形这一自然高边坡普遍现象的地质特征和变形形迹。并综合分析了该高边坡的变形破坏机制 ,探讨了其稳定性。研究结果表明 ,实例高边坡是一处于轻微变形阶段的变形体 ,其存在不会对工程建设产生重大影响。

Abstract: A lot of facts from field investigations show that a time-dependent deformation of a high rock slope could occur before its instability. Accompanied with this process, a potential slIp surface develops gradually in the slope, and finally cut through due to progressive failure along it or some triggering factors. In this paper, the phenomena of time-dependent deformation of a slope on the left bank of Yalong River are described in detail. They reveal that the slope has experienced a long-term deformation and its mechanism can be considered as a slIp along the weak bed plane and buckling on the foot of the slope. Further evidence indicates that the deformation of the slope is quite light, since the slope is under a stable condition at present.
