摘要

基于JC法提出了地下结构的动力可靠性分析方法

建立地基土-地铁隧道非线性动力相互作用的有限元分析模型

将地基土-地铁隧道结构体系视为平面应变问题

采用Davidenkov动力本构模型和动塑性损伤模型

分别模拟土体和车站结构混凝土的动力特性

分析在地震动作用下地铁隧道结构的应力特性

进一步研究其动力可靠性

得到隧道结构的可靠度和可靠指标

以此评价地铁隧道结构的可靠性。结果表明:隧道结构上部右侧45°位置处的可靠性最低

下部右侧45°位置处的可靠性较低

这与隧道结构的拉应力反应的分析结果一致;基岩输入近断层地震动Northridge波和Chi-chi波时

由于地震波的脉冲效应

隧道结构的动力可靠性最低;总体而言

在0.1 g和0.2 g地震动作用下

隧道结构的可靠性足够

结构安全可靠。

Abstract

Based on JC method

the dynamic reliability analysis method of underground structure is presented. Considering the influence of soil-station structure interaction for 2D finite element analysis

the nonlinear dynamic interaction of soil-tunnel structure is modeled. In the modeling

dynamic Davidenkov model is used for simulating dynamic characteristics of soils

and plastic-damage model is used for simulating dynamic characteristics of station structure concrete. The stress characteristics of the tunnel structure under ground motion is analyzed. Furthermore

dynamic reliability of the tunnel structure is analyzed deeply. The reliability and reliability index are obtained

so that

the reliability of the subway tunnel structure is evaluated. The result shows that: the reliability of the upper right side of the tunnel structure at a 45° position is the lowest

and the reliability of the lower right side of the tunnel structure at a 45°position is lower. It is consistent with the stress response of the tunnel structure. When the near fault ground motions of Northridge wave and Chi-chi wave are input

the dynamic reliability of the tunnel structure is the minimum because of the pulse effect of the earthquake wave. Overall

under the 0. 1 g and0. 2 g ground motion

the tunnel structure reliability is high

so it is safe and reliable.
