This document verifies that groundwater flow principles are correctly implemented in PLAXIS. Poroelasticity theory, first introduced by Biot (1941), counts for coupled hydro-mechanical processes. The presented verification example studies the case of a drilled vertical borehole in saturated soil formation (porous rock), subjected to non-hydrostatic in situ stress. PLAXIS results are compared to the analytical solution provided by Detournay & Cheng (1988).
