## at rest lateral earth pressure with sloped backfill (correction to closed thread)

(OP)
thread256-178686: at rest lateral earth pressure with sloped backfill

The thread number referenced above has been closed, but contains a typo in one of the formulas.

Here is the original post from Panars:

"2Panars (Geotechnical)21 Feb 07 10:49
In the US Army Corps Manual on Retaining and Flood Walls
EM 1110-2-2502
http://www.usace.army.mil/publications/eng-manuals...

you can find two methods to calculate the at-rest earth pressure for sloping backfill. The first is
Ko=(1-sin phi)(1-sin beta) where beta is the backfill slope angle."

The corrected formula from EM 1110-2-2502 is:
Ko=(1-sin phi)(1+sin beta)
