摘要：
The seepage field generated by suction penetration of a bucket foundation into sea floor is numerically simulated with a finite element method. The water head and its gradient on both sides of the bucket wall in the seepage field are computed and the results are applied to the calculation of penetration resistance versus penetration depth. Also, allowable suction pressures with various penetration depths are provided for platform installation. The engineering parameters given in this paper were adopted in the design of the first platform (CB2OB) with suction-penetrated buckets as foundations in China. This platform has successfully been launched into operation for the offshore oilfield development at the Yellow River Submersed Delta. (C) 2004 Elsevier Ltd. All rights reserved.
