Urgent help please: Water table during shaft excavation using axisymmetric model

Hi all,  

When doing an axisymmetric excavation, please how to provide water table (assume initial water table at the top surface?  (for this project need to check the full water condition on the retained side so can't use steady flow for water table).

I asked this question because when i provide 2 separate water levels and did analysis the meeting point of these 2 produces tension points because change in the active pore pressure as shown below. 

       <= This is how i provided 2 water levels  and excavation step
