| 摘 要： | The change of the confined aquifer level reflects the pore pressure change, and the pore pressure change of the aquifer is closely related to the aquifer pressure. This paper uses the tidal response of the well water level data in the North China region to calculate the tidal factor of each well and extract the effective water trend information. Then, the volumetric strain of an existing confined aquifer well in the North China region is inverted, and the contour maps are plotted on a half-year scale from 2009 to 2012. Results show that it can reflect the state of stress and strain in deep crust to a certain extent in the North China region.
