Abstract:
Based on load distribution and transferring law under dead load, and applying double borderline transfer function and equal law of work,this paperconcludes a set of simplified analytical recurrence formulas which define curve of axial load and settlement of piles in stratification foundation. With the formulas, the settlements of pile may be analyzed according to distribution condition and configuration of medium around piles,and the curve between axial load and settlement can be de- fined accurately. The iterative formula of stiffness factors on top of pile is also deduced,which may be used to determine the bearing capacity of piles. Two examples prove the effectiveness and correctness of the method.
