| Abstract: | In the tunnel excavated by Shield,it is essential to determine the center line and the limit of the tunnel in the earlier stage of claying a railing. With the example of the limit survey in TA7 bid of Nanjing subway, it is discussed for the method to determine the cross section of the subway tunnel by the routine surveying method , and then the precision is analyzed. |
