摘要
江垭水库蓄水后,大坝及近坝山体产生抬升。所测山体最大抬升21 8mm,120m高程廊道最大抬升34 5mm,为国内外所罕见。为研究抬升的原因及对工程安全的影响,在坝区、坝顶及120m高程廊道内建立了监测系统,进行了较长期的观测,并做了数值模拟计算和室内岩石力学试验,确认大坝可以正常运行。
After the impoundment of Jiangya Reservoir, the dam and its nearby mountainous body appear uplift. The maximum measured uplift of the mountainous body is 21.8 mm and that of the gallery at the elevation of 120 m is 34.5 mm, rare in the world. In order to study the effect of such uplift on the safety of project, the monitoring system has been set up for a long-term observation in the dam area, dam crest and the gallery at the elevation of 120 m. And the numerical simulation calculation and indoor rock mechanics test have been made. It is concluded that the dam can be operated normally.
