Ltd.,Shanghai 200032 China ) ( 2Nanjing Metro Co. Ltd.,Nanjing 210024 China) Abstract line of Nanjing Metro passes through plicated earth layers,such as shallow hill rock layers,acient floodplains,and some parts with to the river bottom. Therefore,many construction methods are used in the period of the tunnel excavation. Among them,three methods are very difficult to operate. The first is shield drilling in shallow embeded clay under the water,the second is the shield-canopy construction in the watery clay under buildings,and the third is blast construction in the excavation of the shallow rock tunnels under the tunnel construction of line,different methods were used to e the difficulties. Firstly,the float-control piles/slabs are appli
