永年地震台水管加速N倾异常分析
Analysis on accelerated northward tilt anomaly of N component of water tube tiltmeter at Yongnian Seismic Station
摘要
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 sys-tem,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 calcula-tion.关键词
