Abstract
A load mechanism and its associated displacements for friction piles driven in a soil subject to regional subsidence is presented. The effect of a surficial crust, which is not under consolidation, is analyzed and to avoid pile emersion, a boundary for the piles safety factor is established. Foundations supported on friction piles, where the foundation slab should always be in contact with the supporting soil, is also analyzed. It is proposed to consider that the load transmitted by the foundation slab be equal to the excavated weight and it is suggested that the increase pile-soil adherence with time, should be taken into account. A maximum value for pile load capacity, in order to avoid emersion, is obtained. Results from measurements, showing the deformation distribution with depth in the clay layers down to 32 m, are shown. Finally, a design example of a compensated foundation supported on friction piles, is presented.

Friction Pile Foundations Subject to Regional Subsidence
St. Louis, Missouri
A load mechanism and its associated displacements for friction piles driven in a soil subject to regional subsidence is presented. The effect of a surficial crust, which is not under consolidation, is analyzed and to avoid pile emersion, a boundary for the piles safety factor is established. Foundations supported on friction piles, where the foundation slab should always be in contact with the supporting soil, is also analyzed. It is proposed to consider that the load transmitted by the foundation slab be equal to the excavated weight and it is suggested that the increase pile-soil adherence with time, should be taken into account. A maximum value for pile load capacity, in order to avoid emersion, is obtained. Results from measurements, showing the deformation distribution with depth in the clay layers down to 32 m, are shown. Finally, a design example of a compensated foundation supported on friction piles, is presented.
