摘　　要：为准确计算超深大直径盾构工作井内衬的受力情况,采用理论计算和有限元的方法,全面分析了底板完建和运行等不同工况下底板和侧壁的受力情况,明确了内衬内力分布形态。计算结果表明:对于超深大直径盾构工作井内衬,采用实体有限元模型能更好模拟工作井受力变形情况,可为同类工程提供借鉴。In order to accurately calculate the internal force of extra-depth and large-diameter shaft,based on the theoretical calculation and finite element software(MIDAS),the force of the bottom plate and the side wall was comprehensively analyzed under different working conditions such as the construction period and operation period.The calculation results showed that the use of the solid finite element model can better simulate the force of the extra-depth and large-diameter shaft,can provide reference for engineering design.
