摘要
吸力锚是近年来在海洋工程中出现并得以迅速发展的一种新型基础形式。然而吸力锚施工中产生的土塞现象对顺利施工和安全使用构成了严重的威胁。文章采用了离散单元法来研究吸力锚施工中的土塞现象 ,并得到了一些结论。圆形刚性颗粒模型是文章中所采用的基本模型 。
Suction anchor is a new pattern foundation that is used in offshore pr ojects. Soil plug that takes place in the course of installation of suction anch or may be harmful to the structures both in installation and in service in many cases. This paper makes use of DEM (discrete element method) and gets satisfacto ry results. The rigid-circle grain model is adopted as the basic model and dynam ic relaxation method is taken for the basic method in the paper.
