根据我国高海拔地区高温热害隧道热力学特性模拟分析,同时结合高海拔地区空气压力低、密度小和含湿量低的特点,建立高海拔地区高温隧道热害预测模型,预测了不同热力状况下的高温隧道热害程度,并根据当地具体条件提出高温隧道热害控制技术。 According to the thermodynamic characteristics of high temperature and thermal damage tunnels in high altitude regions of China, the thermal damage prediction model for high temperature tunnels is established based on the characteristics of low air pressure, low density and low moisture content in high altitude areas. Of the high temperature tunnel thermal harm degree, and according to local specific conditions put forward high temperature tunnel thermal damage control technology.
