| 英文摘要 | Large earthquakes induced different co-seismic water-level responses in Zuojiazhuang and Baodi wells (similar to 50 km apart). Barometric responses and tidal responses are used to explain this anomaly in this study. After analysis, shale was found in the aquifer lithology of well Baodi. The well is found to be significantly influenced by fractures, and has a poor water confining ability. It is likely that the complex fractures or anisotropy of shale lead to a semi-confined aquifer, and as calculated, vertical drainage occurred in the aquifer stratum. Therefore, we separate the 2 wells into 2 models - the horizontal flow model, and the (pure) horizontal flow + (pure) vertical flow model. Because of the influence of fractures, the aquifer medium of well Baodi has a good hydraulic connection with the outside field even before the occurrence of earthquakes, thus, the difference in pore pressure between the well aquifer and the outside field is small, leading to a tiny (or even none) co-seismic permeability increase, and those might be the reasons why the co-seismic water-level changes in Baodi well are always small and unclear. |
