摘要：
Taking the express way tunnel in Zhejiang Province as project background and using MARC Software, the paper simulated whole procedures of dynamic construction of NATM tunnel by the use of 3D FEM. The influence of construction procedures and construction techniques on settlement of arch crown and internal force of structure is studied in the paper. Especially, the mechanical behaviors of steel pipe umbrella and rockbolts are deeply investigated in detail.
