Abstract:: On the basis of the micro-dynamic data of the water level and the analysis of hydro-chemical characteristics of the seismic observational well,and referring to the methods like the step response function of water level and air pressure,the spectral analysis,the leading or lagging of the phase of tidal wave group,and the water-rock equilibrium analysis,we propose a method of judging the groundwater type of the seismic observational well,and the synthetic judgment basis.Then we apply our method and judgment basis to judging the groundwater type in Sichuan-Yunnan region.We find that the groundwater types of seismic observational wells got according to our judgment method differ sharply from the ones judged according to the storage conditions at the time when the wells were built.Thus,we further discuss the reason.
