Abstract:

According to penetration mechanism of jacked pile, the expansion of a series of spherical cavities in semi-infinite space is used to simulate the process of pile installation; and soil is assumed as Mohr-Coulomb material. By using the theory of spherical cavity expansion, imaging method and Boussinesq solution, the surface stresses is corrected; then ultimate frictional resistance and end-bearing capacity can be confirmed respectively. The data from field test show that the effect of friction fatigue during installation is obvious; and the relevant formula of friction fatigue is presented; then the computation formula is deduced based on the factors above. It is proved that this method is feasible because the values calculated by the presented formula with software Matlab6.5 are consistent with the field test results in Taiyuan of Shanxi Province under given depth.

Key words: jacked pile, jacking force, spherical cavity expansion, friction fatigue, penetration
