STUDY OF INFLUENCE OF SOIL PLUG ON DRIVING PILES OF OFFSHORE OIL DRILLING PLATFORM |
|
|
|
|
Abstract Based on the Terzaghi¢s bearing capacity theory for deep foundations，a new approach for soil plug assessment is put forward，in which the surcharge effect and the influence of driving piles on surrounding soil have been considered；and the dynamic effect coefficients are included. The approach has been applied to practical engineering projects；and the calculated results agree with the observed data very well，indicating that the approach can give more reasonable results than the currently used method.
