Construction equipment surcharge Loads
Construction equipment surcharge Loads
(OP)
I'm running a slope stability analysis for a stone causeway.
What surcharge load would be appropriate for a 40 ton dump truck? I'm looking at a spec sheet, and it looks like the total laden vehicle weight is 138 kips, with a footprint of 18.5' x 10.5'. That would get me to a 710 psf loading.
I've seen several references to using 250- 300 psf loading for construction equipment. I'm assuming this range is meant for small bulldozers, etc? Am I on target w/ a 710 psf loading?

I'd neglect any such loading, since it is temporary spot loading and if some slippage starts it would scram out immediately.
Your failure under spot loading is not a circle, but a part of a sphere. Does your analysis method take that into consideration?
