摘要

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1000.44m,地下水位受邻孔抽水严重影响。1982年1月开始观测,1988年11月起塑料厂开始抽水,严重影响观测;2001年8月由于工厂停产停止抽水,观测井地下水动态逐渐趋于稳定。本文分析该井地下水动态年变化规律,计算水位固体潮潮汐因子、观测精度与井孔对地应力响应灵敏度。并对抽水干扰及其前后,地下水动态观测质量的变化进行对比。
The Yong'an Freezing Factory Well,with depth of 1 000.44 m,is the deepest seismological-groundwater dynamic observational well in the coastal region of Southeast China.The ground-water level is seriously affected by the water pumping from nearby well.The Yong'an well began observation in Jan.1982,and the plastic plant started pumping water in Nov.1988,which seriously influenced the normal observation.The plastic plant stopped pumping water in Aug 2001.The ground-water level gradually tends to stable.In this article,the dynamic annual change of the ground-water is analyzed and the tidal factor of the level,observation precision and response sensitivity of the well water level to crustal stress are calculated.As well as,the change of the ground-water observation quality before and after water pumping and the interference of water pumping were compared.
