Cantilevered Soldier Pile Wall - Sanity Check

[Trenno]

Hi guys, haven't touched earth retention in a while and would appreciate if the experts could give me some quick feedback on my methods.

Ended up with a total depth of embedment of 4.5m below excavation level. 600 DIA piles @ 1500 c/c with 150thk shotcrete lagging.

Anyone?

I use 3* pier diameter for resistance, but given your pier spacing is less than 3 diameters I would just center to center spacing of piers for available width of resistance. Also, I wouldn't hang my hat on 1.2*do as the embedment depth for final (ok for estimate), I would calculate it.

Looks ok for overturning but deflections could govern. what is at the top of the wall? A WALLAP analysis would take about 15 mins if you have that software

Also take a look here. I had put together a short post about quick hand calcs.
