摘要：
During the last decades, the increasing number of incidents in road and railway tunnels have attracted public attention to the danger of tunnel fires. These incidents established that quickly accumulating, huge amount of evolved heat impairs the reinforced concrete structures of tunnel linings. Designing of fire bearing linings, it is necessary to understand the behaviour of the linings impacted by bumping heat load. In this paper, the results of our heat load examinations of residual strength (compressive strength and split-tensile strength) parameters on different mixtures of concrete were summarised.
