3 Sided Sheet Pile Wall
3 Sided Sheet Pile Wall
(OP)
This was discussed some time ago and I'm wondering if there is a method out there that other have used. My original thinking was similar to what the previous OP had suggested.

The question is: If you have a sheet pile wall that is not a complete box. Say that it is set into a slope. So you have a long backside then you have two shorter side walls. The long back wall has a waler which spans between the two side walls. There is a reaction now placed on to the side walls. How do you calculate the resistance to this reaction of the side walls?
Thanks!

Did they mean cohesion or what did they use for a normal force?

RE: 3 Sided Sheet Pile Wall
If you utilized walers to distribute the reaction you really would not need to rely on any shear transfer of the interlock assuming each sheet acts individually (atleast I don't think you would).
I guess this problem stated another way:
How could you quantify the resistance of sheet piling used as a deadman. However the sheet piling parallel to the load. For example if you have a cantilever sheet pile wall and you "T" into the back of the wall. You then have walers to connect the sheeting. So now how would you find the capacity of the stem of the "T" to act as a "deadman"?
Maybe the answer to both of these is you don't!
But they both seem like they could work.

RE: 3 Sided Sheet Pile Wall
The way I looked at it was to take the load from the "back" wall into the wales along the side walls. Then I specified welds between the wales and each sheet to transfer the load to the sheetpiles. These were Z sheets, so it was easy in my mind to justify load transfer from the sheetpiles to the soil on the side walls. I looked at the average stress needed along the side walls (just the portion that was in the ground). As I recall the average stress was very low, so it was easy to say that the condition was ok by judgement.
I'm going to take a look at the above link to see what that method recommends.
Anyway, that is my two cents worth.
