Abstract : reviewed are five methods for the analysis of the penetration of jacked - in piles, namely, cavity expansion method, strain path method finite element method, slip line method and calibration model test. after analysis, it is pointed out that it is more rational to adopt sub - statical spatial axisy numerical formulas based on traditional plane - strain cavity expansion method in the analysis. after spatial closed - form solutions are obtained for soil movements, stresses and initial excessive pore pressures generated durihy pile penetration are found out. it is suggested that finite element analysis together with centrifugal model test be used in verifying the results
