系缆墩基础应力的有限元计算

Calculation of Stresses in Mooring Dolphin Footings with Finite Element Methods

为了考虑系缆墩平台和系缆墩基础之间的相互作用,文章利用三维弹性有限元法和三维刚架有限元法计算系缆基础中各个桩的轴力分配。根据桩的极限承载力来计算桩的入土深度。通过工程实例的计算说明它们在实际工程设计中的应用。

To calculate the interaction of the platform of a mooring dolphin and the footings of the mooring dolphin,both the threedimensional elastic finite element method and the threedimensional rigid finite element method are used to calculate the distribution of axial force in individual piles for the mooring dolphin.The ultimate bearing load of the pile is used to calculate its buried depth.The calculation for an example case of a project has demonstrated the methods in the designs for actual projects.
