Can Crest Toppling factor of safety be below 1.5 for retaining walls?

Can Crest Toppling factor of safety be below 1.5 for retaining walls?

Can Crest Toppling factor of safety be below 1.5 for retaining walls?

(OP)
Hello,

I am reviewing a retaining wall project which uses anchor wall software. I understand the minimum factor of safety for crest toppling is 1.5 (NCMA). In the report 1.5 falls under the “Default Minimum”, but the engineers are using different minimums ranging from 0.95 to 1.5 to design their walls. Why?

Would anyone be able to explain to me please why they would have used safety factors below 1.5 for some of their walls?
Leniency with crest toppling?

Thank you!
Tomas

Do you mean overturning?

This discussion should move to the Earth Retention Forum since it is not really concrete engineering. You will have a different audience over there.
