粘土中倾斜荷载作用下深水吸力锚的极限承载力计算研究

Calculation study on the ultimate holding capacity of deepwater suction anchors against inclined load in clays

建立了适用于深水吸力锚的三维弹塑性有限元模型,对粘土中倾斜荷载作用下吸力锚的极限承载力进行了计算,并采用塑性极限法的理论分析对计算结果进行了校核,验证了有限元模型与计算结果的可靠性,为吸力锚在我国深水油气田工程设施应用的前期研究和设计提供了参考。

The ultimate holding capacity of deepwa- ter suction anchor under inclined load in clays is calculated by building a three dimensional finite el- ement model. The calculation result is checked by the plastic limit theoretical analysis, which verifies the reliability of finite element model and calcula- tion results. The findings presented in this paper could be useful for the early study and design of suction foundation neering facilities in for deepwater oil and gas engi China.
