高海拔严寒地区公路隧道保温对于工程的耐久性和安全性有重要影响。而选用适宜的保温材料又是保温体系的关键。经过材料比较,泡沫玻璃的材料特性更适宜于隧道保温工程。实际工程应用的温度数据也表明,泡沫玻璃的保温效果十分显著。
Insulation of highway tunnels in high altitude and severe cold areas has an important impact on the durability and safety of the project. The selection of suitable insulation materials and insulation system is the key. After material comparison, the material properties of foam glass are more suitable for tunnel insulation engineering. Practical engineering temperature data also shows that the insulating foam glass effect is very significant.
