A New Alignment and Breakthrough Accuracy Optimization Strategy in Long Immersed Tunnel Surveys

For ultra-long tunnels, the effective means of alignment and breakthrough accuracy optimization is to measure the gyro azimuths or transfer the coordinates of surface known points or the directions to the inside of the tunnel through vertical shafts or inclined shafts. Compared with bored tunnels, i...
