Description

一种隧道结构多维空间加载火灾试验***及其实施方法 技术领域
本发明涉及隧道结构火灾试验***领域，具体涉及一种隧道结构多维空间加载火灾试验***及其实施方法。
背景技术
随着我国工业化、城市化进程推进，我国交通隧道(公路、铁路、地铁、海底隧道等)的开发利用进入快速增长阶段，隧道交通给我们带来便利，但是由于隧道火灾事故具有蔓延迅速、不易控制、危险性大等特点，也往往容易造成严重的损失；隧道结构在日常运营过程中处于围压受力状态，评估其承载能力对于隧道设计与运营安全具有重要意义。一般可利用反力加载***测定隧道试验模型的承载能力。然而，随着隧道用途的多样化，隧道截面形状不断更新(圆形、矩形、马蹄形、椭圆形、多边形、双圆形组合式断面等)。现有的加载反力加载***通常仅适用于圆形截面隧道模型加载，难以适用于不同截面形状的隧道结构测试需求。
此外，常见的隧道结构火灾试验往往将一辆即将报废的汽车点燃开展实验。该种试验方式一方面浪费资源且污染大，另一方面，试验燃烧过程不可控，且难以模拟汽车移动火灾的影响。另外，火灾试验过程中需要使用到摄像及热像装置获取试验数据与影像资料。常见的高温摄像及热像仪一般是将摄像与热像仪置于火灾高温环境外部(即通常为室温环境)，通过伸进火灾高温环境内部的镜头组件间接成像，此类高温摄像及热像仪缺点是成像视角狭小，且难以兼具热像及测距，不能很好地满足隧道火灾高温环境的使用需求要求。
