Concrete buried tanks Uplift check
Concrete buried tanks Uplift check
(OP)
Dear experts
In case of checking uplift on buried tanks have a heel (cantilever) footing should i take the uplift force equal to the column of water from ground water level till the bottom of the tank into full area of the footing or the displaced volume of water ,it gives to me big different values of uplift force and governed the quantity of concrete.

The tank was reburied and the mound untouched for a year. No word on the fate of the executive.

To follow up on it...
As a newbie I worked on some undg. valve chambers etc. for underground pipeline.
I couldnt make one particular (cca 5x5x4m) work with usual method (displaced volum VS concrete weight only) so my mentor at a time suggested I put 50cm cantilevers (nibs) in the bottom slab and use the truncated cone thing (10 degress...the soil was gravel IIRC so it was fi/3 angle).
Never had to use it again, but I wonder is this thing covered in any codes (never seen it in any geotech books i skimmed trough)? Are there any tables depending on soil type?
