Due to the particularity of working conditions of the port revetment lining and oneness of material used,the revetment engineering is often destroyed because of the action of external load.Based on the new material research,combined superior adaptive performance of flexible cement concrete material with mechanical characteristics of revetment structure,this paper puts forward a new type of revetment lining structure which introduces flexible cement concrete(FCC)port revetment engineering.When the above layer(FCC)thickness is certain,and the lower layer(PCC)thickness changes,the change trend of stress-strain of centre of layers is contrasted through numerical simulation application example.The results show that the flexible cement concrete(FCC)revetment can meet the requirements of bank protection lining,and change trend of stress-strain is small under the action of external load,and PCC is a practical means of revetment lining.
