混凝土坝垂直位移安全监测数据分析

Analysis of safety monitoring data of vertical displacements of concrete dam

为验证某混凝土坝蓄水期能否满足安全要求,结合某混凝土坝蓄水期的垂直位移观测资料,运用逐步回归分析法,构建了坝顶垂直位移统计模型,探讨了各分量对垂直位移的影响。结果表明,水准点监测系统状态良好,统计模型精度较高,混凝土坝垂直位移变化规律正常,符合一般混凝土坝变化规律。

To verify that the storage period to meet the security requirements of a concrete dam, a vertical displacement of concrete dam observation data are combined, stepwise regression analysis are used, statistical models are built of vertical displacement of dam crest, various components of vertical displacement effects are discussed. The results show that the monitoring system works well, the accuracy of statistical models is high and the discipline is normal, which is in accordance with general concrete dam.
