1) shaft lining in bedrock section
基岩段井壁
1.
Ground pressure stress of shaft lining in bedrock section of deep vertical shaft and extra deep shaft is revealed by theoretical analysis,which provides a basis for optimized design of shaft lining in bedrock section.
揭示深立井及超深立井基岩段井壁地压应力的理论分析方法,为基岩段立井井壁的优化设计奠定基础。
2) vertical shaft bedrock section
立井基岩段
4) sidewall sample
井壁岩样
5) 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。
6) sidewall coring,wall sampling
井壁取岩心
