Information on the development of stress and changes in stress was furnished by soil pressure cells installed in the fill over a concrete culvert. The soil pressure cells were calibrated before installation. Pressure-cell readings were taken at various times during and following completion of construction of the fill. Pressure from additional fill material is not always transmitted immediately to the pressure cells. It was more than six months from the time the maximum height of the fill was in place over the pressure cell before the full effect of the full pressure was noted at the pressure cell location. The AAR Type II pressure cells and the Waterways Experiment Station cells appear to be functioning very well. Pressure cell C-8, AAR Type I is inoperative at the height of the fill as is pressure cell C-9, also AAR Type I. With few exceptions there is generally good agreement between measured and theoretical pressures.
