| Abstract: | The ultimate holding capacity of deepwater suction anchor under inclined load in clays is calculated by building a three dimensional finite element model.The calculation result is checked by the plastic limit theoretical analysis,which verifies the reliability of finite element model and calculation results.The findings presented in this paper could be useful for the early study and design of suction foundation for deepwater oil and gas engineering facilities in China. |
| Keywords: | deepwater suction anchor inclined load holding capacity plastic limit method finite element model |
