隧道复合衬砌运营期可靠性评价方法

RELIABILITY ANALYSIS OF TUNNEL SECONDARY LININGS DURING SERVICE LIFE

  • 摘要: 一些隧道的二次衬砌作为重要的结构参与工作,承担荷载。提出了复合衬砌运营期可靠性评价方法,采用不等宽的脉冲随机过程描述钢筋混凝土衬砌的劣化,用施工资料和监测数据+基于连续介质模型的有限元计算+响应面法获得荷载效应的显式,给出了严格意义的可靠性计算公式,并给出算例。

     

    Abstract: For some tunnels, secondary linings are used to carry loads. In this paper, a method is presented to assess the reliability of composite linings during the service life of tunnels. A pulse process is proposed to describe the degradation of reinforced concrete linings. Based on construction records, in-situ monitoring data and finite element analyses, Response Surface Method is adopted to obtain the explicit expressions of load effects. A strict formulation for reliability analysis is given. Finally, the proposed method is demonstrated with an example.
