The concrete service structure in the actual engineering is not only under the action of a single factor,there are at least two and more environmental factors on its impact,a variety of factors on the deterioration of concrete is not a simple superposition,but there is a mutual coupling relationship.Adding fiber can improve the cracking resistance and toughening strength of concrete,limit the crack of concrete and improve the performance of concrete.The research on the behavior change of fiber reinforced concrete under the action of actual multi-field coupling environment can fully identify the application potential of fiber reinforced concrete and provide basis for further engineering application.Through research results at home and abroad at present are summarized for space and time-varying damage of fiber reinforced concrete under the effect of multi field coupling to the latest research situation,points out the research gaps and deficiencies,and put forward the direction of further study,which provides ideas for the research that still needs to be carried out to systematically and comprehensively understand the mechanics and durability of fiber reinforced concrete.
