Abstract: In the paper, the regional stress and the stress state on plane and along profile in Ma-17 well area are calculated using two-dimensional finite element technique of linear elastic theory for studing stress condition affecting sensitivity of water table in this well. The result indicates that there is a stress concentration during perparation of stronger earthquake in North China.
