Numerical Analysis of Compacted Forming Concrete Pile in the Subsea Soil
Based on the present tecnology of pile, a method of compacted forming concrete pile applied in the subsea base is studied. Using the method of finite different the procedure of compacted forming at the end of steel pipe pile has been simulated in the particular geology soil, the effects of the elastic modulus, cohesion, friction and dilation on the compacted behaviour are aquired and the bearing capacity has been calculated. The results show that the ultimate bearing capacity of this pile increases approximate 3 times bigger than the steel pipe pile with the same dimentions, in addition, its curve of Q-S is smooth and ultimate feature point is indistinct, which proves that this tecnology of compacted forming concrete pile is able to increase the bearing capacity prominently.
