Abstract：
Based on the geological conditions and foundation pile longitudinal bearing capacity of urban sub-center of Beijing, this paper carried out an in-depth study on the common foundation pile construction process and proposed the engineering test of carrier pile construction process in this area. It was shown that carrier pile construction process completely satisfies the specification of applicable Method for Engineering Construction Site Management of Beijing, and could meet the construction requirements of urban sub-center pile foundation project, having the worth of application and promotion.
