| Popis: | The paper gives results of field studies on uplift forces on small-diameter columns of steel, concrete, and wood caused by adfreezing in frost-susceptible Leda clay. Adfreeze strength values would appear to be highest for steel and concrete, followed closely by wood. The heaving pattern and the heaving force transmitted are shown to be different for long foundation walls than for isolated columns. This compares favorably with the deformation pattern induced in an ice cover around offshore structures, during a change in water level. Attention is also given to the relative movement of the heaving soil with respect to the structure and the influence of the heave pattern on the transmission of forces. |
