摘要
十三陵抽水蓄能电站上池钢筋混凝土面板堆石坝筑坝料风化严重，沉降变形量极大，通过从设计阶段对坝体沉降变形的认识到对坝体实测变形的较全面的分析和总结，得出如下结论：实测变形与实际填筑情况相一致，基本为上游坝体填筑较下游好，底部较上部好；大坝最大沉降发生在坝轴线附近的1／2坝高处；主压缩变形出现在施工期，坝料随填筑增高而不断发生破碎；坝体填筑完成后，坝体沉降变形仍在继续，这部分变形是蠕变变形．
The rockfills of the upper dam of Shisanling Pumpod Storage Power Station are se-riously winded so that which causes a large settlement, 800 mm of 60 m dam height. Through ananalysis on the practical settlement data monitored and compared with settlement predicted in early design stage, The conclusion shows that monitored settlements are basically coincidence withthe actual backfill condition, upper stream part of the dam is in a better condition than downstream part of the dam, lower part of the dam is better than higher part, the largest settlementhappened in ca. 1/2 height of the dam ,near the dam axis, the rock broken happened contiguous-ly with the backfill height increasing (main compress )and happened gradually after backfill accom -plished (secondary compression).
