摘　　要：以某隧道项目试验段为依托,提出一种钢波纹板后填充混凝土的复合结构二次衬砌,采用有限元数值模拟分析,并与现场监测数据对比等方法,对其结构的力学性能进行研究。研究结果表明:波纹钢混凝土复合结构二衬在位移变形、应力状态、安全系数等方面均符合结构设计规范要求,波纹钢结构具有更好的适应性。通过与监测试验数据对比,运营阶段有限元计算结果与实际应力结果拟合程度较好。Based on the test section of a tunnel project,a composite structure secondary lining with corrugated steel plate followed by filled concrete is proposed,and finite element numerical simulation is used to analyze and compare with field monitoring data and other methods to study the mechanical properties of its structure.The research results show that the corrugated steel-concrete composite structure secondary lining meets the structural design code requirements in terms of displacement deformation,stress state and safety factor,and the corrugated steel structure has better adaptability.By comparing with the monitoring test data,the finite element calculation results in the operation stage fit well with the actual stress results.
