摘要
锦屏一级水电站双曲拱坝是世界已建最高坝,首次蓄水按库水位1 700 m、1 800 m、1 840 m、1 880 m四阶段已成功蓄至正常蓄水位。监测结果表明大坝变形、应力应变、渗流、渗压符合一般规律,量值在设计控制指标范围以内,枢纽工程各建筑物工作性态整体正常;库岸总体安全;水位在1 880 m附近持续1个多月后,各监测数据趋于平稳。
The arch dam of Jinping Ⅰhydropower station is the highest dam in the world. In accor-dance with the established scheme, the reservoir water level has reached normal high water level now.The monitoring result shows that the stress and strain, deformation, seepage, osmotic pressure of dam arein line with the general law, the value is under the designed value. The behavior of the project is normalon the whole and the reservoir bank is stable. The water level of the 1 880 m has lasted more than 1month, monitoring data tends to be stable.
