将三种粘土的保水曲线与膨胀压力的最佳可用估计值进行比较，以确定是否获得了预期的等效值。 3 pF 和 4 pF 之间的膨胀压力与保水力一致。 pF 4 以上，粘土变得不饱和；低于 pF 3，膨胀压力估计中未考虑的吸引力使保水性低于膨胀压力。概述了计算理论膨胀压力的方法。
Water retention curves for three clay soils are compared with the best available estimates of swelling pressure to determine whether the expected equivalence is obtained. Between pF 3 and 4 swelling pressures show agreement with water retention forces. Above pF 4, the clays become unsaturated; below pF 3, forces of attraction not accounted for in the swelling pressure estimates make water retention lower than swelling pressure.A method for calculating theoretical swelling pressures is outlined.
