摘　　要：为了探究双峰寺水库蓄水变化是否会产生地形变化,利用双峰寺水库2020年、2021年蓄水数据与承德地震台VP型宽频带倾斜仪测值进行相关性研究。通过计算承德地震台宽频带倾斜仪8时整点测值与水库蓄水数据间的皮尔逊相关系数及建立载荷模型,得到水库蓄水引起的地形变量。结果表明,双峰寺水库蓄水对承德地震台宽频带倾斜仪日常观测曲线趋势性影响较小,且二者间相关性不大;蓄水载荷变化对宽频带倾斜仪测值影响不显著,二维、三维载荷模型结果趋于一致。In order to explore whether the water storage change of Shuangfengsi reservoir will produce topographic changes,this paper studies the correlation between the water storage data and the VP broadband inclinometer data of the Chengde Seismic Station in 2020 and 2021.By calculating the Pearson correlation coefficient between the 8 o’clock data of the broadband tiltmeter at the Chengde Seismic Station and the reservoir impoundment change,and building the load model,the topographic changes caused by the reservoir impoundment were obtained.The results show that the impoundment of Shuangfengsi reservoir has little influence on the daily curve trend of broadband tiltmeter at the Chengde Seismic Station,and there is little correlation between them;the impact of changes in water storage load on broadband inclinometer data is not significant,and the results of the two-dimensional load model and the three-dimensional load model tend to be consistent.
