| Abstract: | As the component in NATM,the secondary lining technique has been used widely in permanent tunneling.In every step,this technique was applied to Jiao-Jin Highway Tunnel.Based on the secondary lining practice in this tunnel,this paper discussed the demand of primary support for secondary lining,the proper operation time in high-pressure deformation and ordinary soft and weak surrounding rock,and some problems in NATM.It also obtained some useful conclusions |
