摘要/Abstract

摘要： 铜街子水电站,在水库蓄水后,以18坝段分界,呈现出左侧坝段沉降、右坝段抬升的罕有异常状况,大坝上抬量从左至右逐渐增大。通过开展监测资料信息挖掘,以及构造地质水文地质状况分析,断定该异常状况系因独特的构造及水文地质,在水库蓄水后引起深层承压水变动,导致的区域连锁反应。电站自蓄水以来,水位一直保持在正常蓄水位左右,坝址区内的渗流状态已经稳定,抬升变形也逐渐趋于稳定,不会影响到大坝安全。

Abstract: :Rarely seen abnormalities including settlement on the left and uplift deformation on the right with section 18^# as dividing line were found at Tongjiezi Hydropower Station after reservoir impoundment. Through mining the monitored information and analyzing the structural geology and hydrogeology condition, we concluded that the abnormalities are regional chain reactions resulted from the unique structure and hydrogeology, which caused the change of deep confined water after reservoir impoundment. Since the impoundment, water level has remained normal, seepage in the dam site has stablized, and the uplift deformation gradually tends to be stable. At present it is not yet a threat to the safety of dam.

Key words: Tongjeizi, uplift of dam body, safety monitoring, correlation analysis, confined water
