Hello sir, how 100 KN of PWP was applied, was it based on the calculation of 2m depth or it was a random value. furthermore, for a 2m depth, I think it would be around 20000N/m2.
First of all, thanks for your sharing,but I have some doubt about how to simulate environment pressure of water，I will appreciate it very much if you can give me some tips.
@@pranjlm Did you use it to define that，I heard about someone used geostatic stress to simulate it，if you have any ideas，we can communicate each other. Thanks!
You can change the PWP conditions. Make an end PWP zone where you want to drain the water. That will work. You can make a specific drainage line with high permeability in the middle of the dam.

very useful video. I have one question, how do you combine tectonic stress in this model? how to calculate the effective stress?
Regarding tectonic stress, i don't. Regarding effective stress, subtract total stress from pore water stress.

What is the sign convention for pore water pressure!
Positive pore pressure means there will be seepage. Negative pressure will mean suction.

you have to combine the hydrostatic pressure with atmospheric pressure in PWP BC dialouge
@@pranjlm Thanks for your reply，but I have no ideal about PWP BC，can you describe it further more.Thank you very much!
@@wenzyc3645 i meant pore pressure in the boundary condition dialogue.
@@pranjlm Did you use it to define that，I heard about someone used geostatic stress to simulate it，if you have any ideas，we can communicate each other. Thanks!
I am not talking about geostatic stress. I am talking about pore water pressure boundaries. For example, at free boundaries, the pwp will be zero.
Sir why didn't you defined the pore pressure for the entire domain, i mean there must some initial pore pressure inside every pore?
Yes, you can define it based on the literature or experience. I omitted it to keep it simple.
How to apply uplift pressure under concrete gravity dam ?
You can create suction via PWP difference.
I'm doing mtech project on FEA analysis on dam I'm having some doubt regarding how to simulate drainage gallery behaviour into the dam can u help?
You can change the PWP conditions. Make an end PWP zone where you want to drain the water. That will work. You can make a specific drainage line with high permeability in the middle of the dam.
@@pranjlm can u share your mail id i want to share my results. It would be very helpful

@@pranjlm thank you
how to consider water table in soil
Apply PWP conditions or assign predefined field saturation.
Sir,
Please explain elaborately how to calculate pore water pressure in PVD embedded clay soil.
I will soon upload a video on this topic
@@pranjlm
Thank you sir.
Would you please give your email ID Sir?
