Structural design knowledge: the towering steel base anchors the top surface of what design requirements?

     Towering steel base which the top surface of the anchor design requirements?
     A design should take into account the upper anchor steel precision requirements, the actual construction of the concrete foundation and the possibility of the possibility of installation and adjustment of construction to determine the accuracy requirements, and the tower bottom anchor holes accordingly expanded, easy to install and adjust. After the anchor hole expansion should be adjusted after installation is complete plus welding thick pads to meet the requirements of fixed bolts.
     B double nut locking bolt is appropriate.
     C anchors shall be buried deep tension reinforcement anchorage length calculations.
