Underground tank . ASME Sec Vlll div 1
Underground tank . ASME Sec Vlll div 1
(OP)
I have underground tank with 0.8 m diameter and height 1.7 m . HLL is 1.4 m . Specific gravity of liquid is 1.2 . Internal pressure is Atm and static pressure of liquid . Roof is bolted cover .The design code is ASME sec Vlll dev .1 .
1) how I calculate the thickness of tank ( shell , bottom ).
2) the design of bolted cover has to take the effect of soil load ( density of soil is given ) . Can Anybody advise me how I can consider soil load in design of bolted cover ( roof ) and is it possible to do this using compress software ? Also concrete pavement thickness is given .
Thanks.

Calculate external pressure due to the soil and use that as external pressure on the tank.
Whether Compress can handle the cover- I don't know, the pressure is reversed from a normal flange, and it may or may not be set up to handle that.
Also note that applying a pressure vessel code to non-pressured vessels may give you unreasonable results at times.
