Lateral pressure from stockpile

[hamza41]

Hello,

Can anyone tell me how to calculate the lateral pressure coefficient on the wall in this case ? I couldn't find any reference in the internet. I'm not sure it's the same for a retaining wall with infinite soil ((1-sinΦ)/(1+sinΦ)).

Thank you.

You could use the Cullman method for irregular backfill.

Unless there are very strict controls in place I'd design it as infinite soil method with full height plus a surcharge of material stacked at its angle of repose.

Thank you for your replies.

I was thinking it could be something similar to what is considered for stacking towers. [link file:///C:/Users/hamza.mami/Downloads/Loads_for_Design_of_Stacking_Tubes_for_Granular_Materials%20(5).pdf]Link[/url]

I'm with George. If it can be stacked, it will be stacked. I did one for corn cobs one time. The existing wall was falling down since the cobs were piled to the max.

I forgot to precise that the maximum height of stockpile we can have is the wall height.

How will the stockpile be controlled? I've seen failed walls because to move the stockpile, they used a front-end loader. Those can really multiply the stockpile load.

Actually,the pellets are accidently falling from a conveyor at the same level of the wall and they are accumulated near to the wall.

Is there a reclaim conveyor in the ground as well? Or will they scoop it up with a front end loader?

No it will be removed by small loaders.
