摘　　要：积石峡水电站面板堆石坝坝址为左右岸不对称的复式河谷地带,为预防面板堆石坝发生不均匀沉降,施工中采用坝基处理、分期分区填筑、坝料洒水碾压、坝体浸水等措施。经后期监测,仅发生了约2 mm的不均匀沉降,取得了良好的控制效果。The CFRD dam site of Jishixia Hydropower Project is seated in the compound valley with asymmetric banks. To prevent the CFRD from occurrence of uneven resettlement, proper measures are taken in construction such as foundation treatment, embankment at stage and zone, roller compaction of the embankment materials with water sprayed, dam body inundated in water, etc. After the late measurement, 2mm uneven settlement occurs only and an expected uneven settlement control is achieved.
