Abstract
Oil extraction from oil sands, a non-traditional crude oil resource, is attracting attention as the oil price fluctuates due to recent economical and political issues. Many oil sands sites are mainly located in the polar regions. For plant construction to extract crude oil from oil sands in harsh environment of the polar regions, fast and simple installation of plant foundation is necessary. However, typically-used conventional foundations such as drilled shafts and driven piles are not suitable to construct under cold temperature and organic surface layers. In this study, helical piles enabling rapid and simple constructions using small rotary equipment without driving or excavation was considered. The helical pile consists of steel shaft and several helices attached to the steel shaft; therefore, the behavior of the helical pile depends on the number and shape of the helices. The effect of the helices' configuration (number and diameter of helices) on helical pile behavior was analyzed based on the numerical analysis results.
