摘要

运用有限元数值方法对浅埋、偏压隧道的开挖施工方案进行了数值仿真研究，对比研究了两种不同开挖条件下围岩和支护结构的受力与变形规律的差异，对施工过程中可能产生的变形效应对围岩稳定性的影响展开了深入探讨，给出了既符合隧道设计规范、又满足稳定性要求的施工方案；研究结果可以为浅埋、偏压条件下的隧道设计、施工提供有意义的参考

Abstract

In accordance with the instance of shallow-buried tunnel in a highway project

it was analyzed that numerical simulation on excavation construction of the entrance of the shallow-buried tunnel under the uneven rock pressure. Firstly

the computational models in FEM were built in differently excavating cases which were often adopted in practice. Then the stability and the different distribution of deformation and stresses of the rock and liner of tunnel were discussed in the two excavating case. In the end

according to the analysis and results the preference of effective measures of excavation is suggested. In sum

the improvement scheme and research redound to the effective control of the stability of shallow-buried tunnel under the uneven pressure from stratum during construction.
