摘要
黄金坪水电站坝址区边坡多为工程地质条件复杂的松动破碎岩体高边坡,在建设过程中总体较为稳定,产生变形破坏迹象较大的只有引水隧洞及泄洪洞进口区边坡。根据引水隧洞及泄洪洞进口边坡工程地质条件、变形监测资料,分析边坡开挖后应力变化规律,对岩体破坏模式进行研究。
Most of the slopes in Huangjinping Hydropower Station project area are high broken rock slope with complicated engineering geological condition. In the construction of Huangjinping Hydropower Station, these slopes are stable on the whole and only the slope at the intake of diversion tunnel and flood-discharge tunnel has significant trend of deformation failure. Based on the engineering geological condition and deformation monitoring data of slope at the intake of diversion tunnel and flooddischarge tunnel, the stress and deformation rules of slope after excavation are analyzed and the failure mode of rock slope is also studied.
