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 is used to calculate temperature gradient field and heat flux of tunnel structure fire resistance layer under different temperatures, and the results of lightweight aggregate concrete fire resistance layer is compared to those of fire-retardant coatings commonly used. This analysis will provide technical basis for the application of lightweight aggregate concrete under high temperature environments in the future.
