摘要
模型参数取值的不确定性会对衬砌结构耐久寿命预测结果产生较大影响。作者对结构耐久寿命影响因素进行敏感性计算、分析和排序。据此,在衬砌耐久性分析时可对影响因素区分对待、重点考虑,确保结果可靠性。
During the course of predicting the service life of tunnel lining, the uncertainty of the parameters could affect the results. In this paper, the sensitivity of parameters is calculated, analyzed and ranged. Based on these effects, different parameters could be differentiated and considered for the purpose of holding important ones and ensuring the w.liability of the results.
