Abstract: The author analyzes the cause and possible influence of interface joints at elevation 218 m of Fengman new dam, and introduces the deformation and seepage monitoring items. To study the changes of deformation and seepage values, reliability check of monitoring data is the first step. Then statistics of eigenvalue is studied, spatiotemporal distribution curves are drawn and correlation analysis is made. Finally, the analysis conclusion is obtained.

Key words: Fengman new dam, deformation, seepage, analysis of monitoring data

摘要： 分析了丰满新坝高程218 m层面缝的成因及其可能影响，对增设的变形及渗流监测项目进行了介绍。为了判断该层面变形及渗流监测值的变化情况，首先对监测数据进行可靠性检查，然后对各监测物理量测值进行特征值统计，并绘制时空分布曲线，进行相关性分析，最后得出分析结论。
