[TowerTalk] RE: Soils

[Chanel1096@aol.com]

"Normal Soil" is not a vague term, it is defined in TIA/EIA-222-F.  Following 
is the definition:

7.1.3 Normal Soil - A cohesive soil with an allowable net vertical bearing 
capacity of 4000 pounds per square foot and an allowable net horizontal 
pressure of 400 pounds per square foot per lineal foot of depth to a maximum 
of 4000 pounds per square foot.

(Note: Rock, noncohesive soils, saturated or submerged soils are not to be 
considered normal soil.)

So as you can see 'Normal Soil' is rather well defined.  If you are looking 
for some more detailed information that is public available go to

http://www.usace.army.mil/inet/usace-docs/eng-manuals/cecw.htm

Which is a link to the US Army Corps of Engineers list of engineering 
manuals.  There are several on soil topics but they can get rather technical.
Hope this helps some.
