| 摘 要： | 永年水管倾斜 NS 分量2012年9月出现加速 N 倾异常，从洞室环境、仪器系统、供电系统、环境干扰等方面进行调查和分析，采用三维集中荷载模型，计算采石场、挖土场等荷载变化对水管倾斜观测影响的理论值，采用定性与定量相结合的方法，判定此项异常应为周围环境干扰造成的荷载变化所致。

| Abstract: | There is accelerated northward anomaly of water tube tiltmeter NS component at Yongnian Seismic Station from September 2012.We survey the cavern environment,instrument system,environmental disturbance,and power supply system,calculating the theoretical values of load influences to crustal tilt observation by three-dimensional concentration load model, while the load influences include quarry and soil excavating.We primarily judge the anomaly caused by environmental disturbance through qualitative analysis and quantitative calculation. |
