| Abstract: | Finite element method of offshore bucket foundation platform suction penetration seepage field is discussed in this paper. The reliability of this method has been proved by comparison between the results of model test and finite element analysis model. The method is applied to the computation of the seepage field. The computed results give the allowable suction pressure varying with the penetration depth, which can be used for guiding the suction pressure control of the platform installation. The results also give the seepage water head and water head gradient on both sides of the bucket wall corresponding to the allowable suction pressure, which can be used for the computation of the penetration resistance. |
