The building pile technical specification (JGJ94-2008) has provided the formula to estimate the vertical ultimate bearing capacity of single concrete precast pile with static sounding data, Although being issued for years, the Specification was not used frequently in the engineering practices in Kunming, where the estimating of the vertical ultimate bearing capacity of single pile in most engineering practices are still according to experimental parameter, This text estimates the vertical ultimate bearing capacity of single pile with static sounding data for a high-rise building in Kunming, and compares this result with the result which is estimated by the traditional algorithm based on experimental parameter, comes to a conclusion for reference.
