| 1 | This Part covers methods of precision survey for setting out the tunnel alignment. Since the tunnel excavation is normally started from many faces for expeditious completion of the work, it is essential that the excavation proceeds precisely along the pre-determined alignment. Even a slight deviation from the correct alignment, particularly in the initial stages, may lead to non-coincidence of the centre lines of the various stretches of a tunnel at the meeting points. This revision has been brought out to bring the standard in the latest style and format of the Indian Standards. In addition, Figure 1 has been revised for better clarity. | |
