PY Curves

Unlike for the TZ and QZ curves the shape of the PY curves which are output depend upon the method which has been selected for a particular layer. For further information on the shape of the PY curves refer to the lateral soil methods section. The PY curves that are actually plotted can be controlled by adjusting the upper and lower depths for plotting on the PY curves tab, as shown below. When the depths have been adjusted the plot can be refreshed by pressing the replot button.

The ultimate pressure is also plotted and can be found under the PY curves tab.
