This article establishes the model of a high-pile bent spatial structure by the finite element software of ANSYS to calculate and analyze the changes of the pile displacements along its length under horizontal forces.Comparing the results from the model with that from the normative formula，it is proves that the two are consistent with each other.At the same time，the law of the distribution coefficient about the horizontal force applied to the bent is researched，and it is found that the horizontal force also has some influence on the distribution coefficient.
