The friction in the soil need to be able to resist the shear forces transferred by the foundation, otherwise the foundation will slide on top of the soil.
EK522
If no drainage is possible from a soil, because the soil has been sealed off, or because the load is applied so quickly and the permeability is so small that […]
EK519
As long as the stresses remain below the preconsolidation load the soil is reasonably stiff, but beyond the preconsolidation load the bahavior will be much softer.
EK518
When reloading a soil there is probably less occasion for further sliding of the particles, so that the soil will be much stiffer in reloading than it was in the […]
EK511
Undrained shear strength is the shear strength of a soil when sheared at constant volume.
EK495
Secondary compression is the change in volume of a fine-grained soil caused by the adjustment of the soil internal structure after primary consolidation has been completed.
EK494
Primary consolidation is the change in volume of a fine-grained soil caused by the expulsion of water from the voids and the transfer of stress from the excess porewater pressure […]
EK489
The effective stress in a saturated represents the average stress carried by the soil solids and is the difference between the total stress and the porewater pressure.
EK486
The effective stress is the average stress on a plane through the soil mass.
EK485
The porewater cannot sustain shear stresses, and therefore, the soil solids must resist the shear forces.
EK479
Porewater pressure is the pressure of the water held in the soil pores.
EK455
A point of equilibrium, called the neutral plane, exists where the negative skin friction changes over into positive shaft resistance. This is where there is no relative movement between the […]
EK308
If the retaining wall moves toward the soil, a passive soil pressure develops.
EK307
Under soil pressure, the retaining wall may deflect or move a small amount from the earth, and active soil pressure develops.
EK51
Vertical pile resistance to lateral loads is a function of both the flexural stiffness of the shaft, the stiffness of the bearing soil in the upper 4D to 6D length […]
