摘　　要：基于薄壳稳定性理论和三维大变形有限元数值模拟技术,提出了隧洞钢衬抗外压能力的数值计算方法,并成功应用于江西省九江市马头水库隧洞钢衬失稳破坏的机理分析,从而验证了所提出方法的合理性和可行性,弥补了钢衬结构抗外压能力现有计算方法的不足,具有一定理论价值.Based on the stability theory of shell and 3-D large deformation finite element numeric simulation technology, numerical calculation method of capacity of resistance external pressure in tunnel steel liners is raised, and applied successfully in the anal- ysis of the damage mechanism which was leaded to the instability of the tunnel steel liner on Matou reservoir of Jiangxi province. The rationality and feasibility of the method proposed above is validated, the shortages consisted in the existing calculation methods of capacity of resistance external pressure on steel liner structure is made up.
