摘要
结合某隧道工程混凝土强度无损检测的实例,建立隧道衬砌结构的非线性有限元模型,分析隧道衬砌结构的抗力随时间变化的特性,评估隧道衬砌结构在承载能力和正常使用极限状态下的可靠性,并对隧道衬砌结构的使用寿命进行预测,可为隧道工程的决策提供参考依据。
Based on the nondestructive testing for concrete strength of one tunnel project, a nonlinear finite element model for the tunnel lining structure is established to analyze how the resisting force of the tunnel lining structure changes over time, evaluate the structure reliability when the ultimate bearing capacity is required, and predict the service life, which will provide the references for similar tunnel projects
