HCSB TBM屏蔽块初步设计与结构性能分析

摘要

Preliminary design for HCSB TBM shield was introduced. Structural analysis was carried out in accordance with RCC-MR standard, under four typical load conditions. Preliminary results show that the overall deformation is very small, and the primary and secondary stresses are all well below the allowable values.%介绍了HCSB TBM屏蔽块的初步设计，根据RCC-MR相关标准，在4种典型工况下对TBM屏蔽块的结构性能进行了分析和校核。计算结果表明：所有工况下的整体形变都较小，一次应力和二次应力均满足RCC-MR标准。
