摘要
通过建立自升式平台的开孔桩腿有限元模型,对桩腿开孔时在自存和作业工况下的应力进行了计算,并对开孔后桩腿结构强度与屈曲强度进行了校核。计算结果表明,开孔后的桩腿符合安全规范。
A FEM model of the pile is constructed. The stress of the pile with holes in the survival and operating modes, is calculated numerically, and the structural strength of piles is checked. The buckling strength of the piles is also checked. The calculation shows that the piles with pores are safe according with the rules.
