Methods of dynamic stability critical load of foundation pile

摘要

In this paper based on principle of elastic stability, The calculating formulas for dynamic stability loads of foundation piles under axial dynamic load were conducted‥ The effects of differences restrict of pile end and pile length ratio and pile diameter and level resistance of soil and exciting frequency on dynamic stability of foundation pile are discussed. The some measure of reduce vibration of piles are advanced. It is hoped that these may prove to be some value in practical engineering.
