Failure slopes through geogrid
Failure slopes through geogrid
(OP)
I have a retaining wall 6 concrete blocks high with 5 layers of geogrid inbetween. I am looking at using two strengths of geogrid.
If I use the stronger geogrid for the bottom 3 layers. It will have sufficient strength to counter the failure slope starting at the the bottom of the 6th block. Can I then design the top two layers of geogrid shorter using a failure slope starting at the 3rd block?
Thanks

Secondly, though, you have the global stability. You have made no comments on the nature of the ground onto which you will place your wall. You need to be congnizant of this too. The design of the present job I am on failed to account for this.
Check out the MESA wall computer program that you can get. It is put out by the Tensar group. You can download it. Also, there is an Italian company with a program too. Some recent texts give good examples of how to design.
Best regards.

You can look for BS8006 as a design guide for such walls, or the FHWA report 82 on the matter.
