Use of “singularity” elements to model pore pressures in the vicinity of free‐draining loaded surfaces, immediately after application of loads at these surfaces is discussed. One‐dimensional consolidation is considered. Comparison of numerical results with the exact solution shows that use of specially designed elements approaching “singularity” may succeed in reducing the error in pore pressures.
