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
I think you can check the on-demand video about the common pitfalls on performing dewatering analyses: https://learn.bentley.com/app/VideoPlayer/LinkToIndividualCourse?LearningPathID=113626&CourseId=129954&MediaID=5019074

Dear Mr. Stefanos,
The mention video about the de-watering which the retaining system has the embedment depth. We can define another water level and assign to excavated side (I'm normally doing like that when doing excavation with embedment depth as shown below).
But the case I was asking above is the shaft excavation which don't have embedment depth. Need to excavate and cast the circular section.
So i need to how to make dewatering for this (as mentioned above when following this second water level idea there was error as there is no embedment depth and failure occured in the transition zone).
Dear Mr. Stefanos Papavasileiou
Any reply please if you are free.
Dear Mr. Micha van der Sloot
Can you help this one also, please?
You should consider what happens with the water and pore pressures around your shaft. Only changing the pore pressures in one area without changing areas that are directly connected, is not realistic and will lead to local out-of-balance. Either performing a groundwater flow analysis or adjusting the pore pressures to be more realistic in the adjacent soil volumes would solve this.A webinar with details is here:learn.bentley.com/.../LinkToIndividualCourse
