| 摘 要： | 针对龙背湾面板堆石坝首次蓄水后期坝体实测沉降量大于理论计算值的问题，在分析了堆石体内部沉降变化过程、分布规律、特征值大小等基础上，建立沉降监测统计模型，评价了大坝内部沉降规律，并讨论了坝体实测最大沉降量偏大的原因，为龙背湾面板堆石坝未来安全度汛和水库蓄水提供参考。

Analysis of Inside Settlement Characteristics of Longbeiwan Face Rockfill Dam |
| |
| Abstract: | Aiming at the problem that the measured maximal inside settlement of Longbeiwan face rock fill dam is greater than the corresponding calculated value during the first impoundment period, according to the monitoring data of the dam settlement, the variation, distribution and characteristic values of inside settlement are analyzed, which serves as a foundation to establish the statistical model of the dam settlement. Then the regularity of the dam settlement is evaluated and the issue why the maximal measured settlement is greater is discussed. The conclusion can provide valuable technical support for flood protection of Longbeiwan face rockfill dam in further water storage of the reservoir. |
