Buoyancy of underground tank
Buoyancy of underground tank
(OP)
I know buoyancy is crucial item to the design of an underground tank. I've been asked to design a tank that is 20'x40'x10' deep. I've been informed by the civil engineer that the "water table is well below the tank". Is that all the information I may need? Is that information enough? Is there such thing as say I need to be designing for a 100 yr water table? I would assume at some point the water table would be higher than the base of the tank. Thanks

Do you know what kind of soil profile that you are dealing with? Don't forget to consider the possibility of a "perched water table".

If the civil refuses, you could assume the worst, design the tank for a groundwater table at the ground surface, and see where that gets you, as Ussuri says. This will likely lead to an expensive design, and someone will make the decision to either go ahead with the more expensive design or do the right thing and get a geotech out there.
Is this a remote area? Why is it quicker to design a tank than for a geotech to get out there and provide you with some real information? This sounds like baloney. Somebody's making a stupid decision for the wrong reasons.
It's not in your interest to base your design on a vague, oral statement by another engineer. If you have documentation, you'll be much better off when things go wrong. If it's not written down, it didn't happen.

jike-the soil is mostly dense clay. With that said, I can't believe the water table is always going to be below the base of the tank as the civil engineer suggested.
