Derive PWP on failure plane of active wedge behind retaining structure

Derive PWP on failure plane of active wedge behind retaining structure

(OP)
Hello all,

I'm looking for some help regarding the following issue - any advice would be greatly appreciated.

I am trying to express U (the integral of u on the slip plane) in terms of W (weight of wedge), theta and r_u (pore pressure ratio)- for now, assuming beta=0 and alpha=90 (see attachment). I have spent a long time attempting this, but believe it is time I asked for help.

W, theta and r_u are all knowns.

Thanks in advance,

Moe
