摘要
文章基于河南某隧道工程的冒顶塌方情况及其主客观原因,通过建立有限元数值分析模型,模拟分析了隧道通过冒顶塌方段的结构稳定性及施工力学行为,并提出了相应的处治措施,为今后隧道的冒顶塌方施工提供了依据。
Based on the roof caving landslide and its cause in one tunnel construction in Henan,the article analyzes the structure stability and construction force behavior through building a finite element analysis model.It also proposes the corresponding countermeasure, which provides evidence for future construction.
