| 摘 要： | 首先综述了土石坝沉降统计预报模型的概况，在比较分析了几种简单曲线模型后认为，S型生长曲线较为符合土石坝的沉降规律。拟合预报效果良好。然后，结合面板堆石坝的施工特点，并考虑库水位升降速率及各因子耦合的影响，建立了面板堆石坝沉降统计预报模型，经实测分析表明，该模型精度高，拟合效果好。

| Abstract: | Statistic prediction models of settlement for earth rock dams are briefly summarized. Comparison of some simple curve models shows that S type growth curve accords well with the settlement of earth rock dams and has good prediction results. Then, a statistic prediction model of settlement for concrete face rockfill dams (CFRD) is developed considering construction characteristics of CFRD, rise and drop rate of water level, and coupling influences of various kinds of factors. Comparison shows that the model fits well with high precision. |
