二滩水电站二号尾水渠内侧边坡稳定监测

During the excavation of the inner slope of No. 2 tailwater channel, some kinds of monitoring instruments were established and worked away for a long term about six years.The monitoring data for the inner slope stability was analyzed especially by the multipoint displacement gauge. The creep mechanism of slope and the effects of reinforcement by bolts were also discussed.
