ABSTRACT
Measurements from the cone penetration test are analogous to parameters used in assessing the static component of the soils pile driving resistance. This paper presents comparisons of pile driving data from 610 mm open ended pipe piles driven through lake clays into underlying glacial till, with estimates of driving resistance using the web-based software, IMPACT. IMPACT uses a continuum-based soil model that explicitly separates internal and external shaft friction in the soil-pile model. CPT based expressions for evaluating the static resistance to driving include factors that account for end condition, friction fatigue and differences in the diameter of the CPT and the pile. Evaluation of static tension load test results requires additional estimates of setup and relative contribution of driving resistance from the soil plug.
