The wedge angle in these calculations is 59 degrees. The pore pressures on the blade C-D are almost equal to the pore pressures on the front of the wedge A-C, which they should be with a blade angle of 60 degrees and a wedge angle of 59 degrees. The pore pressures on the front of the wedge C-A are drawn in red on top of the pore pressures on the blade C-A and match almost exactly.
