摘要
分析了万全等4口自流井水位阶变、固体潮幅度与水柱高度的关系。结果表明,当含水层所受应力状态不变,水位观测条件相同时,水位阶变、固体潮幅度与水柱高度有正相关关系。从而证明了自流井水位对含水层应力应变的响应能力与水柱高度存在正相关关系,即水柱高度(动水位)不同时,水位对含水层应力应变的响应灵敏度不同。
The relation between water level step-variation of artesian well, earth tide amplitude and height of the well water was studied based on analysis of four artesian wells. The results shows that a positive correlation exists between the well water level step-variation, earth tide amplitude and well water height when the stress condition of the aquifer is constant and measuring method of water level is identical. Thus the positive correlation between the response capacity of artesian wells, aquifer stress and strain, and well water height is proved, that is when the dynamic well level is different, the response sensibility of well level to the aquifer stress and strain is also changed.
