| Abstract: | In view of the falling block defect existing in the unlined tunnel of electrif ied railway,the reinforcement measures using high strength,insulation,corrosion resistance and f lame retardant aramid protective network were studied.Taking No.8 tunnel on the Fengtai-Shacheng railway as an object,the defects of unlined section in this tunnel were introduced.The reinforcement measures and unsolved problems were analyzed.It was proposed that the aramid protective network should be used to reinforcing the surrounding rock.The physical properties of the aramid protective network were verif ied through experiment and the construction technologies of tunnel reinforcement were described. |
