I am making a concrete sleeper wall and am unsure of the current structural integrity (I am not a civil engineer) specifically regarding the width of each terrace.
My retaining wall will be made from concrete posts, and sleeper slats with rebar as a reinforcer:
I hope that my rudimentary drawings provide enough information.
I have a 5 degree lean back on each terrace of the wall, and each post, and slat is reinforced. However, I do not know how to determine if 4' for each terrace will cause integrity issues. If possible, I'd like to go down to 3' per each terrace. Is there a way to calculate this, or a rule of thumb for these types of retaining walls? Is there a point where I have to use geo-grid reinforcement?
