Abstract:On the basis of the theory of elastic crack,the reflecting earthquake effect of well water level in the confined aquifer is studied by using numerical simulation method.The simulated results demonstrate that the confining condition of well-water bearing system has heavy influence on reflecting earthquake effect of water level change,and the observation quality is directly affected by the leaking level on the sides of aquifer and the height of water head.When the system is confined well,the change of observation water level has a linear relation with water head change.Moreover,for earthquake prediction purpose,in a good well-water bearing system the good penetrability is also one of the important factors to affect water level change,it is effective if the system has a high penetrability.
