摘要
针对隧道采用三导坑法和上下台阶法施工的特点，按照其施工步骤采用Phase2软件对其开挖和支护过程进行动态数值模拟分析，并通过对两种施工方法的比较，以达到配合和指导设计与施工的目的。
Aiming at the features of the 3-heading construction method and Top-bottom benching tunnelling method, in the light of construction steps, the paper analyses the dynamic numerial simulation during excavation and support in tunnel construction and then compares these two methods by Phase 2 software so as to direct the design and construction.
