| 摘 要： | 以上海外环线越江沉管隧道为背景,用通用有限元程序模拟火荷载作用下沉管结构的稳态温度场的变化情况。采用三维有限元模型,分析温度场在不同空间的发展变化情况,从而更直观的掌握温度在隧道横截面上的分布情况,为隧道的防火设计和救灾工作提供依据。分析时考虑了混凝土热工参数随温度变化的非线性关系。

| Abstract: | Based on the Outer Ring Tunnel in Shanghai,the analysis of thermal field under fire loading was carried out by finite element method.It is presented the temperature distribution on the cross-section by a three-dimensional model.During the analysis,concrete is regarded as nonlinear inelastic material and its changes of thermal parameters are also considered.Which provides a basis for the fireproof design of a tunnel. |
