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。

Rarely seen abnormalities including settlement on the left and uplift deformation on the right with section 1 8 #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 ab-normalities 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 nor-mal,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.
