| 摘 要： | 在分析研究地倾斜观测资料时,为反映观测曲线的真实变化,需要剔除干扰因素的影响。该文通过整理分析河北省水平摆、垂直摆、水管仪等地倾斜观测资料,将河北省地倾斜干扰因素主要分为观测系统类干扰、观测环境类干扰以及气象因素类干扰。其干扰形态主要表现为变化趋势转折、变化速率改变、固体潮畸变、台阶、毛刺和突跳变化。

| Abstract: | In order to reflect the real change of observation curve, it is necessary to eliminate the influence of interference factors when analyzing and studying ground tilt observation data. By sorting out and analyzing the observation data of horizontal pendulum, vertical pendulum and water pipe meter in Hebei province, the interference factors of ground tilt in Hebei Province are mainly divided into observation system interference, observation environment interference and meteorological factor interference. The disturbance patterns are mainly manifested in the turning of change trend, change of change rate, distortion of solid tide, step, burr and sudden jump. |
