Abstract:
In order to explore a new way to reduce the adverse influence on the effect of sinking-pile process, the technique of pipe-pile with hole has been proposed. Based on model constructed by FLAC3D, the varieties of the relationship of excess pore water pressure have been compared and analyzed between pipe-pile without hole and the star of pipe-pile with hole during static sinking-pile. Simulation results show that the maximum of static pressure pipe-pile with hole of excess pore water pressure is smaller than the maximum of static pressure pipe-pile without hole of excess pore water pressure. It is proved that pipe-pile with hole is more conducive to the dissipation of excess pore water pressure, and provided a reliable theoretical basis for the application technology of pipe-pile with hole.
