Online Civil Engineering Test - Tunnelling Test

The following tunnels were constructed in different countries for different purposes :
1. Emperor Claudius built the first Roman tunnel
2. The first highway tunnel was constructed in Hungary
3. The first underground railway tunnel was constructed in Great Britain
4. The first navigational tunnel was constructed in France.
The correct chronological development of these tunnels is:

In case of railways,

For initial surveys of tunnels, the following activities are involved:
1. Marking portal point with concrete pillars on the ground
2. Marking tunnel obligatory points on the topographical maps
3. Preliminary setting of the tunnel on the topographical Survey of India maps
3. Driving lines between the fixed obligatory points.
The correct sequence of the activities is :

For transferring the tunnel alignment through shafts, we adopt the following steps :
1. Hanging two or more plumb lines in the shaft
2. Determining the bearing of the plumb lines i.e. plumb plane
3. Suspending a 35 kg weight by each plumb line
4. Immersing the weights of both the plumb lines in the buckets containing water.
The correct sequence of steps is :

For B.G. single track railway, the height of the tunnel above top of rails should be

The difference of heights of the tunnels above rail tops of BG and MG tracks is kept
