Tunnel entrance processing measures between shield originating and receiving of SMW
As a matter of fact,shield originating and receiving is a critical and difficult point in shield tunneling construc-tion.However,SMW enclosure structure is regarded as the shield originating and receiving tunnel entrance,which increa-ses its construction risk.Based on the above-mentioned construction conditions,the paper analyzes risks existing in shield originating and receiving process,introduces the tunnel entrance processing measures and receiving methods of SMW en-closure structure.As a result,it not only strengthens the shielding construction safety,but also reduces shielding con-struction limit,and ensures smooth shield receiving as well.
