Soil Pressure on Buried Vessel

I would recommend "Buried Pipe Design" by A. P. Moser & Steven Folkman. This, in my view, is the best textbook on buried structures available.

where will the water table be on this pressure vessel? If the soil is waterlogged, the tank might feel buoyancy and want to float upwards when empty, albeit gradually. A huge number of buried tanks do this in floods.

3400 - 1250 /25 /12 = 7 feet of soil =~1200. a safety factor of 3 means you need to make it strong enough to withstand 3000 pounds per square foot. So this tank needs to be well built.

a search finds these hits, and in them you may find a reference you can use.

Get a straight wall bucket. Fill it with the soil that will be on top of the tank. Measure the height or depth of the soil in the pail. Calculate the area of the bucket. Weigh the bucket with soil in it. Now you can calculate the weight per square mm at the measured depth. Calculate the area of the tank "shadow". This is roughly a rectangle 2500mm x 6000 mm. Multiple the "shadow" area x the weight of a square mm from the bucket. Multiply this weight by the depth 3400mm/depth in pail. This is slightly more than the tank would see due to rounded ends but fairly close with a positive error.

The weight of the soil on the tank is structural and will not affect the pressure inside the tank unless it were to crush it.

Hi prashant,

I have just carried out design of 10 nos of buried vessel. You can use EEUMA 190:2000 to calculate the soil pressure.

I just calculated, for you case and

Soil Weight shall be 120 tons and external soil pressure shall be 105 kg/m2. I have considered soil density as 2000 kg/m2.

Please tell me if you have any doubt.

Dear Mehta Sir,

Can u please send me the copy of EEMUA 190:2000? Either can u please send me the sample calculation report of soil pressure calculation?

Thanks in advance........

Dear Mehta

I am interested the same way as Markand

I thankfully request EEUMA 190:2000 copy to my email address

Thanx

EEMUA 190:2000 can be purchased here for $257 USD !!!

Dear Metha Sir,

I have seen your post regarding buried vessel. I need to design horizontal buried vessel of diameter 1500mm and length 5750mm.hence can you send that document of EEUMA 190:2000 to understand.

Be careful about external pressure and uplift force while designing the buried pressure vessel.

uplift force tends to make vessel to float.

external pressure=psi=0.433*depth(buriel) in ft*g

uplift force=lbs=vessel of volume in cubic ft*62.4 and consider that vessel is empty

buriel depth/height is from ground level to the bottom of vessel.
