1) number of shaft segments
井壁分段数
1.
For the analysis of global stability of a bored shaft during construction,a mechanical model with the initial bending imperfection has been setup,which considers different influencing factors,such as the varying stiffness of shaft,the number of shaft segments,the flexural rigidity of shaft connections,the distribution of axial loads,etc.
针对钻井法施工阶段固井前变刚度井壁结构整体稳定性问题,引入初始弯曲缺陷,建立固井前井壁结构稳定性分析的力学模型,该模型考虑了井壁分段数、节间连接刚度、井壁刚度分布、井壁轴向荷载分布等因素。
