Article Preview

Based on the bearing capacity behavior and load transfer mechanism of super-long pile in soft soil, the three-stage hyperbolic softening model is presented as the load transfer function of pile-side soil, and tri-linear model is introduced to simulate the characteristics of sediments in pile end. The differential equations are established by dealing with the states of static equilibrium, with considering the character of layered stratum and pile-soil interaction. The analytical solutions on different states are obtained by power series. Based on transfer matrix method, soil mechanics and elastic theory, a set of analytical equations and calculating method for the axial load-settlement curve of pile top in layered ground are established. Lastly, the calculating parameters are obtained by theoretically approaching to actually measure load-settlement curve in soft soil area. The calculating contrast to adjacent test pile is carried out by the method and the results are satisfactory.
