| 摘 要： | 通过对宁波地震台ZK03井动水位9年多的观测资料分析,发现该井动水位观测中主要存在3个方面非人为因素干扰引起的异常现象.①强降雨干扰引起的异常,特征为测值阶跃式上升,但变化幅度不大,易识别;②气压突变引起的干扰,为测值脉冲式向上突跳,但不多见;③公用数采接触不良干扰,引起的是整点测值大幅度上下振荡,结果造成观测数据无效...

| Abstract: | Through analyzing dynamic were 3 kind of anomaly phenomenon water level observation data for 9 years in ZK03 well, there caused by non-human interference factors. ① The anomaly caused by heavy rain was rising in steps with little variation amplitude; ② The interference caused by flip-flops in air pressure was impulse jumps and seldom appeared ; ③The interference caused by public data-gathering section in poor contact, as the main interference factor, was oscillating ups and downs drastically in hour data curve and made the observation data invalid. In addition, the sampling interference of analog water radon observation appeared one impulse downward in everyday minute curve regularly. |
