Earth Grading Terms
Earth Grading Terms
(OP)
I have some doubts in earth grading.
What is the expansion of these following terms.
PVI STA , A.D , K, PVC,PVI,PVT
For a labour camp , I have to design soakpit for 300 members.
Can we go for One big soak pit or something like a soak
trench.

AD= don't know, probably don't need to know
K= a measure of the "sharpness" or abruptness of the curve, never had much use for this one
PVC= beginning of the vertical curve (point of VC)
PVI= point of vertical intersection
PVT= point of vertical tangent, where the curve ends
good luck

It sounds as though you may be trying to use road design software to design and compute earthwork quantities of a "pit". This is probably not the best application of that software. Maybe I'm reading your statements incorrectly.
Please expand on the term "soakpit" and its use relative to a "labour camp". If we know what you are trying to accomplish we can probably better help you address your issues.

Please tell me the procedure to find out the Road Work
Qty using the above terms.
b) Desining of Soakpit is a different issue and not connected with the above

Basically, when designing a road profile, if the grade changes between two segments (greater than a 2% grade change) you need to employ a vertical curve to allow a transition from one grade to another rather than have abrupt angle changes. It provides for a smooth transition between grades.

That raw earthwork data then needs to take into account the thickness of the road section (example: 3" Asphalt + 10 " aggregate base) and the amount of shrinkage (or swell) expected from the soil type.
There is also specialty software that addresses just earthwork such as AGTEK, but Land Development Desktop also has an earthwork volume calculation component.
