摘要

为考察隧道衬砌在火灾高温下的变形性能

利用ABAQUS有限元软件建立了HC基准升温曲线下衬砌环的三维分析模型。分析了隧道衬砌结构在火灾高温下的温度场分布规律

以及钢筋混凝土衬砌结构变形情况。研究了地面超载、土体侧压力系数、火灾持续时间、峰值温度及升温速率对变形的影响。结果表明:地面超载较小时

衬砌拱顶随温度升高而接近围岩

反之则远离围岩;拱腰位移随地面超载的增大而不断增大;土体侧压力系数越大

拱顶越向外移动

而拱腰则越向内移动;火灾持续时间越长、峰值温度越高

拱顶越远离围岩

拱腰越靠近围岩;升温速率对衬砌升温初期的变形影响较大

后期影响不显著。

Abstract

To study the deformation performance of tunnel lining under high temperature of fire

three-dimensional analysis model was built using ABAQUS finite element software

in which HC temperature curve was used as a reference heating curve.The distribution of temperature field of tunnel lining structure and the deformation of reinforced concrete lined diversion tunnels were analyzed.Parametric analysis was done including following factors influence:ground overload

the coefficient of lateral pressure

fire duration

peak temperature and heating rate on deformation.Results show that

when the ground overload is small

the vault will be close to the surrounding rock with the temperature increasing

and vice versa.The displacement of the hance increases with increase of overload.With increasing the coefficient of lateral pressure

the vault will move outside and the hance will move inside.The longer the fire duration or the higher the peak temperature

the vault will be further from the surrounding rock and the hance will be closer to it.The heating rate has great influence on the deformation of the tunnel lining in the initial stage of thermolysis and has no significant influence at later stage.
