- Abstract
A total of 27 piles were installed at the Engineering and Physical Science Research Council soft clay test site at Bothkennar, Scotland using the continuous-flight-auger boring technique. Twelve of the piles of different lengths and diameters were tested in axial compression, using the others as reaction piles. Various testing programmes were employed to investigate relationships between axial load, movement and rate of movement. Strain measurements were facilitated by installing exten"someters in the piles, thus enabling the distributions of load and shaft resistance down each pile to be evaluated. Shaft resistances were found to be approximately constant even though the clay is known to increase in strength with depth. Peak shaft resistances were found to be dependent on rate of movement while ultimate shaft resistances were dependent only on magnitude of movement.
