Alignment in tunnels refers to the precise positioning and orientation of the tunnel in relation to the surrounding terrain and other structures. It involves ensuring that the tunnel is constructed in a straight line or along a specified curve, as well as at the correct depth and alignment with other tunnels or infrastructure. Proper alignment is crucial for the structural integrity and safety of the tunnel, as well as for ensuring that it meets design specifications and requirements.

Tunnel Alignment is a survey that determines the location of the tunnel inside the ground. It is the process of establishing and maintaining the correct direction, elevation, and grade of a tunnel during its construction. Alignment surveys are typically performed using theodolite, total station, or GPS (Global Positioning System) equipment.
The alignment of a tunnel is critical to its safety and functionality. A tunnel that is not properly aligned can be difficult or impossible to use, and can pose a safety hazard to users. Tunnel alignment also has an impact on the cost of construction, as a tunnel that is not properly aligned may require more excavation and/or more materials to complete.
The following are some of the factors that can affect the alignment of a tunnel:
- The geology of the area
- The presence of underground utilities
- The design of the tunnel
- The construction methods used
It is important to carefully consider all of these factors when planning and constructing a tunnel to ensure that the tunnel is properly aligned.
Here are some of the steps involved in a tunnel alignment survey:
1. The surveyor will first establish a control network of points around the tunnel. These points will be used as reference points for the alignment survey.
2. The surveyor will then use a theodolite, total station, or GPS to measure the location of the tunnel and compare it to the control network.
3. The surveyor will make any necessary adjustments to the tunnel alignment to ensure that it is correct.
4. The surveyor will then prepare a report that documents the alignment survey.
