摘要

汶川地震发生后,江口电站进水口边坡监测结果显示边坡表面位移较小,深层位移较大,但测斜仪位移分布曲线较光滑,且震后边坡位移变化较小,说明进水口边坡基本稳定。测斜仪位移分布曲线是否出现Z形突变,以及位移—时间过程线有无明显增长,可作为边坡稳定的依据。
The monitoring results of water-intake slope of Jiangkou Hydropower Station after Wenchuan Earthquake show that the surface displacement is small and the deep one is large,however,the displacement curve is smooth,and the variation of displacement is small,indicating that the water-intake slope is basically steady. Whether or not there occur Z-type mutation of displacement distribution curves and obvious increase of displacement-time curves can be used as the criterion for the slope stability.
