Surcharge load examples
Surcharge load examples
(OP)
Hello everyone,
I am looking for example for retaining wall design with one strip loading as surcharge. I have some books discussing the Lateral Pressure on Retaining wall due to strip loading but it did not give examples on it, but the formula itself.
Been scanning some internet infos regarding this but it showed 2 types of formulas, the with PI and the one without it. I dont know what is the right formula
Another is that i believe that the formula is derive from Boussinesq method, but i just want to have some examples on how did this formula derived from the said method.
I will appreciate any help
thank you very much

This page of the book relates the given charts for Boussinesq-like pressures on the backplane of the wall due to point or line loads to experiments of Gerber (1929) and Spangler (1938).

Look also the first page at top right. You see there the common assumption of the affected zone by some point load. This same figure can be also seen at the

in the same context of helping to determine the position of the resultant of the active pressure in the backplane of the wall. So the simplified zone of pressure would coincide with the one for the noncoherent backfill of CTE (see post above). All this related to Culmann-like determination of the active pressure. The assumptions of the zone of the wall seem so quite accepted for the case.
I have not found yet a quite precise derivation of the simplified loadings, but may have in some of the geotechnical books that I have in the cabinet I access but few times a year. If find something, will say.

Note that the loading in the strip loads needs not be merely vertical, can also have an horizontal component (say, friction against skid action).
