Keywords: Tunnel fire resistance layer, lightweight aggregate concrete, high temperature effect, finite element analysis. Abstract. Fire resistance of tunnel structure is paid more and more attentions in recent years. Lightweight aggregate concrete has low bulk density and good thermal insulation property. This paper is first time to propose the design of lightweight aggregate concrete as fire resistance layer for tunnel. Thermal analysis function of ANASYS14.0 finite element analysis program

This analysis will provide technical basis for the application of lightweight aggregate concrete under high temperature environments in the future.
