| 摘 要： | 对比于桥水库库容变化与蓟县地震台DSQ型水管仪观测数据表明,水库容量对水管仪长周期趋势性变化影响不大,蓄水和泄水过程中库容量变化与水管仪观测数据不存在相关关系。根据近场三维不规则形状荷载模型,对于于桥水库3次蓄水和3次泄水过程,定量计算库容变化对蓟县地震台DSQ型水管倾斜仪观测影响的理论值,结果表明,库容变化引起的水管仪倾斜值与实际观测数据变化幅度相比小得多,库容改变不足以对水管仪倾斜观测造成显著干扰。该分析结果可在观测资料异常判定中提供参考。

| Abstract: | Compared with the reservoir capacity and the DSQ-type water pipe observation data, it shows the that reservoir capacity change has little influence on the long cycle trend of the Jixian Seismic Station. There is no correlation between the change of storage capacity and the observation data of the water pipe instrument. According to the three-dimensional irregular shape load model of the near field, the theoretical value of the change of the capacity of the reservoir during three times storage and three times discharge process of the Yuqiao reservoir vs the observation of the DSQ type water pipe instrument of Jixian Seismic Station is calculated. The results show that the slope of the water pipe caused by the change of the reservoir capacity is much smaller than the actual observation data variation. The storage capacity change is not enough to cause significant interference to the water pipe tilt observation. The analysis results can provide a reference for anomaly determination of observation data. |
