摘要
采用“水位调和分析(M2波计算)”程序,对天津张道口地震台张道口-1井模拟、数字化水位内在质量变化进行了对比研究。从高频干扰、周围井孔的地下水开采、仪器零漂、探头位置与观测精度变化的关系、仪器自身原因5个方面分析了影响张道口-1井数字化水位内在质量的因素,并提出了数字化水位在日常观测中的注意事项。
With the program of ＂the water level harmonic analysis （M2 wave computation）＂, we contrasted and analyzed the intrinsic quality change of the simulative and digital water level of Zhangdaokou-1 well in Tianjin seismic station. Based on 5 aspects of the high frequency interference, the under ground water mining of the bore-hole around it, null shift of the instrument, the relations of the probe position and the observation precision change, the instrument, we analyzed the intrinsic quality factors of digital water level affecting Zhangdaokou-1 well, and put up with the notice item of the digital water level in the daily observation.
