| Abstract: | This paper adopted the method of finite infinite element to carry out the calculation and analysis of an offshore bucket foundation suction penetration seepage field. It offered the calculating method of distribution regulation to the bucket foundation suction penetration seepage field, fluxing velocity distribution and hydrostatic strength sloping declination which support the design of offshore bucket foundation platform with soil background. The practical examples show that the calculation results are satisfactory. |
