Because of soft foundation soil it was necessary to use two-stage construction for a double-track railway embankment varying in height from 21 to 33 feet. Effective stress methods of analysis were used and piezometers were installed in the foundation soil to indicate the pore pressures. Pore pressures measured during the first-stage loading indicated that the second stage could be added to complete the embankment about a year after the first stage. Measurements of pore pressures continued during the second stage loading so that a continuing check on stability could be maintained. The embankment was successfully completed.
