WebThe factor of safety with relation to retaining wall sliding is 0.6. This factor of safety is unacceptable. In order to increase the F.S., we can design a number of combinations including adding a key beneath the footing, increasing the footing width, and using tie-backs. Also, note that soil above the footing in front of the wall was not ...
