Abstract: This paper presents a computation method for a new type of retaining structure—the anchor pile with a pull rod. The formulation has been performed according to the difference principle and with the help of fundamental knowledge of strength of materials and matrix algebra. This method is easy to understand and to operate, since it is very simple. It is reasonable for not only the mutual function between the pile and the elastic foundation but also that of the pile and the pull rod is considered.The author has extended the computing formula and proved that this method can be applied not only for the computation of the anchor pile with a pull rod but of the anchor pile without any pull rod. The computation is much simple especially for the later. The author has computed the anchored bulkheads in the port engineering by means of this method. And compared with the customary one, the method introduced here is also possible.
