  • Design guidelines for predicting the axial capacity of piles in sand have long been the source of considerable debate due to the geotechnical profession’s inadequate understanding of pile behavior. Analytical studies, alone, cannot resolve the uncertainties in axial capacity predictions due to the complex nature of pile behavior in sand. This chapter presents some of the factors which occur during installation and loading of pipe piles in sand, along with their potential impact on axial capacity....

  • Abstract. Design guidelines for predicting the axial capacity of piles in sand have long been the source of considerable debate due to the geotechnical profession’s inadequate understanding of pile behavior. Analytical studies, alone, cannot re solve the uncertainties in axial capacity predictions due to the complex nature of pile behavior in sand. This chapter presents some of the factors which occur dur ing installation and loading of pipe piles in sand, along with their potential impact on axial capacity. ...

  • Many offshore structures are subjected to overturning moments due to wind load, wave pressure, and ship impacts. Also most of retaining walls are subjected to horizontal forces and bending moments, these forces are due to earth pressure. For foundations in such structures, usually a combination of vertical and batter piles is used. Little information is available in the literature about estimating the capacity of piles under uplift. In cases where these supporting piles are not vertical, the behavior under axial pullout is not well established.

  • This paper presents in situ tests which were performed on both single piles and pile groups, loaded to failure, with the aim of studying the pile group effect of piles embedded in multi-layered foundation. Strain gauges were installed along the shaft of 10 m long steel pipe piles, with a diameter of 143 mm. The influence of loose sand layers on the group effect in case of friction piles was evaluated. The experimental results indicated that the influence of sand layers was evident, and the group factor was calculated to be 1.237.
