永安冷冻厂深井是东南沿海最深的地震地下水动态观测井,井深1 000.44 m,本文介绍了永安井的地质构造及正常动态变化规律,通过对永安井数字化水位观测资料的分析,总结日常观测过程中可能遇到的多种干扰因素,从自然因素、外界环境因素、人为干扰因素、仪器自身因素等典型表现,提高对非地震前兆干扰因素的识别,以便更好地排除干扰,提高仪器观测资料质量。
Yong’an Freezing Plant Deep well is the deepest earthquake observation groundwater well of 1 000.44 m deep along the southeast coast. This paper introduces the regularity of geologic structure and normal dynamic change of Yong’an well. Through the analysis of digital observation data of water level in Yong’an well, summarizes the daily observation process May encounter a variety of interference factors, from the natural factors, external environmental factors, human interference factors, the instrument itself factors such as typical performance, to improve non-seismic precursors to identify interference factors in order to better eliminate interference and improve the quality of instrumental observations .
