| Abstract: | In the present paper, mathematical models, analyzing and calculating methods as well as centrifuge tests of stability analyses of piles have been reviewed. Attention is mainly paid to the modes of instability and the mechanism analysis, included the pile instability base on Euler buckling theory, directional instability of driven piles, pile instability during earthquake liquefaction, dynamic instability of piles and post-bucking analysis of piles. Finally, a further study is presented briefly. |
