摘要：
Roadway insulation and active cooling supporting structure is a complex system, and the mechanical properties play an important roal in its safety. Analyse the shotcrete layer pattern heat insulation structure by Midas-GTS software, calculation results shows that tensile stress zone appears in the top and bottom of heat insulation layer, while the will compressive stress area appears in two sides of the roadway insulation layer; in the case of 500m buried depth, heat insulation layer material, such as vitreous micro-bead, can well meet the engineering mechanical strength requirements.
