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。
積石峽水電站麵闆堆石壩壩阯為左右岸不對稱的複式河穀地帶,為預防麵闆堆石壩髮生不均勻沉降,施工中採用壩基處理、分期分區填築、壩料灑水碾壓、壩體浸水等措施。經後期鑑測,僅髮生瞭約2 mm的不均勻沉降,取得瞭良好的控製效果。

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.
