List of Contributions

The surcharge (backfill load) contributes to the bearing capacity (Terzaghi's equation) with the term qNq, where q is the surcharge. This is a major contribution to the bearing capacity, especially for frictional soils with little or no cohesion. Ignoring this term is conservative for cohesive soils, ...

When you say "surcharge height", do you mean the backfill that is placed around and above the pad (the term qNq in Terzaghi's equation)? ------------------------------ Panos Kiousis A.M.ASCE Associate Prof Colorado School Of Mines Golden CO ------------------------------

Lateral bearing pressure accounts for the geometry (diameter) of the pole. Imagine the Terzaghi bearing capacity, having a triangle under the footing followed by a transitional zone, and then followed by the passive zone. The passive resistance assumes that the pole is infinitely wide and, as a result, ...

The paper of the link that follows references design wind pressures for a wind turbine in Mongolia. The authors of that paper (included email addresses) come from Mongolia. They should be able to give you the answer, if the information in that paper is not sufficient Panos http://citeseerx.ist ...
