Abstract: Horizontal loading capacity of inner steel plate compound shaft lining is influenced by the multi-factor. In this paper , The influence factors of horizontal loading capacity be based on analyzed of similarity theory, Through the Simulation calculation and analysis of typical-parameters, Get the main influence factors of horizontal loading capacity. through the analysis on the results of numerical simulation,a calculation formla of estimating the horizontal loading capacity of inner Steel Sheet and High-strength steel fiber reinforced concrete shaft linling was obtained, In the calculation formula the diversified factors relating to the horizontal loading capacity have been considered. Finally, Using theoretical calculation analysis and verified by the model examples , That formula has applicability and reliability.
