密云水库白河主坝测压管监测数据变化分析

Analysis on Change of Pressure Gauge Pipe Monitoring Data of Baihe Main Dam of Miyun Reservoir

连续10a监测密云水库白河主坝测压管10号管水位数据动态变化特征,基于逐月5日、10日、15日、20日及25日的连续观测建立数据集,利用描述性统计数学原理进行计算分析,得到系列数据的特征值,并绘制测压管水位数据动态变化图谱。通过分析得到结论如下:白河主坝测压管监测数据的变化特征显著,月际分布不均匀,年际变化波动较大,在丰水期与枯水期的差异较大。但由于数据体量所限,单点测压管监测数据不足以反映水库的整体变化,未来应向大数据实时可视化监测方向开展研究。

By monitoring the dynamic change characteristics of the water level data of the No.10 piezometric pipe of the main dam of the Baihe River in Miyun Reservoir for ten consecutive years,a data set was established based on the continuous observations on the 5th,10th,15th,20th and 25th of each month,using descriptive statistics The mathematical principle is used for calculation and analysis,the characteristic value of the series data is obtained,and the dynamic change map of the piezometric water level data is drawn.The conclusion is that the monitoring data of the piezometric pipe of the main dam of the Baihe River has obvious variation characteristics,the monthly distribution is uneven,the inter-annual variation fluctuates greatly,and the difference between the wet season and the dry season is large.Due to the limited data volume,single-point piezometric monitoring data is not enough to reflect the overall changes of the reservoir.In the future,research should be carried out in the direction of big data real-time visual monitoring.
