Retaining wall question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi all;

I am designing a 10' retaining wall where the soils report gives
a passive value of 400 psf and a coef. of friction of 0.3 for bedrock.
The report states that these are allowable design values and have a factor
of safety of 1.5.my question is whether this is the same safety factor
required for sliding by the ubc, or are the ubc factors in addition?
