Abstract
Based on the unified limit force profile, an analysis referring to the behavior of cast-in-place concrete pipe pile with large diameter (PCC) under lateral load was set up through performing a series of numerical simulations of models with either different pile size or different soil strength parameters using FE. Furthermore, three parameters (Ng, α0 and n) [Read More: http://ascelibrary.org/doi/abs/10.1061/47631%28410%299] involved in the unified limit force profile of soil were back analyzed, and reasonable ones for PCC analysis were determined. A simplified method for calculating the ultimate bearing capacity of PCC under lateral loads was established paying respect to the approximate equivalence between the depth of the location of maximum moment and that of plastic slip line. The calculation results based on this method were compared with FE solution a good agreement was found. Therefore, it could be useful for the design and analysis of PCC under lateral load.
