@lexpatrie I asked about a specific tank as in the image shown, not in general, so I was surprised you mentioned shotcrete etc. But thank you for the additional info.
Freeboard details (level) are specified by a civil/hydrology engineer, at least in my country.
Seems you didn't read all the...
@lexpatrie thanks for this. Not sure about the shotcrete comment, here the case is wide excavation and in-situ shuttered concrete wals, so that shouldn't be a problem.
About the tank being empty during floods is certainly questionable, I will have a look and try to find out how much water is...
Yes, that is all correct, had no senior engineers here to give me valuable advice on this topics so thank you for sharing this with me.
Sounds fair saying there is no friction in case of extended foundation (except along the thickness of the foundation), however the failure surface is going to...
About the weight of the soil which is acting on top of the footing, in calculations I'm using uplift force as:
H x B x L x gama(w), where
H - depth measured from the level of ground water to the bottom of founds,
B - foundation width
L - foundation length
gama(w) - water specific weight...
Hi guys,
I'm having a storm water retention tank which is 4.85 m deep in the ground, it is in a flood area, therefore ground water is considered full depth of the tank, base is about 51x21 m.
It is open, no top slab, as a pool. Bottom slab is 0.6 m deep, walls are 0.3 m. My question is if I use...
