Results of the settlement calculation, and the load capacity of single pile in theory are much more different than the static pile compression experiment on the construction sites. Therefore, it is essential to set up the settlement relations, bearing capacity of single pile in theory, experiments of SPT and experimental methods such as compression of static piles. As a result, this article helps the designer to adjust the calculation results of the settlement and bearing capacity in accordance with the process of theory, which is suitable for works on construction sites.
