Concrete Wall failing to be supported by Segmental Retaining Wall
Concrete Wall failing to be supported by Segmental Retaining Wall
(OP)
One of the architect has come out with a option of putting a Segmental Retaining wall in front of a failing poured in place retaining wall the ht of this wall is 7.0ft at the highest point and its retaining parking lot.They are not willing to take down the existing wall considering that its already is leaning and looks like its moving forward.They have asked me to look at the option of putting a SRW wall in front of it. My concern is i still have to account for the forces of active earth behind the concrete wall i have to put a geogrid/use bigger blocks to design. I want to get some thoughts do i have to take any other forces. I am assuming as if the existing retaining wall is not there but given that the client does not want to remove this wall i am not able to come out with a bigger block to design for a 7.0ft wall.Any other options?

I'd agree with MSEMan - why is the original wall failing?
f-d

i checked wall is failing because of Base sliding its moving forward not leaning(not a bearing failure).There are some block manufactures like unilock and redirock they have a big machine place stones whereby they can go as high as 7.0 to 8.0ft without grid some of these system have front to back depth of almost 2.0ft.They original wall was designed about 15 to 20 years ago.
