Civil Surveying and Leveling Part-1

Test Preparation on Civil Surveying and Leveling Part-1

1.

To avoid large centering errors with very short legs, observations are generally made

1To chain pins
2By using optical system for centering the theodolite
3To a target fixed on theodolite tripod on which theodolite may be fitted easily
4All the above

2.

Different grades are joined together by a

1Compound curve
2Transition curve
3Reverse curve
4Vertical curve

3.

Which of the following methods of theodolite traversing is suitable for locating the details which are far away from transit stations?

1Measuring angle and distance from one transit station
2Measuring angles to the point from at least two stations
3Measuring angle at one station and distance from other
4Measuring distance from two points on traverse line

4.

6.

The chord of a curve less than peg interval, is known as

1Small chord
2Sub-chord
3Normal chord
4Short chord

7.

1+50 m, +86.6 m
2+86.6 m, -50 m
3+50 m, -86.6 m
4+70.7 m, -50 m

3D/4
4D/6

10.

Contour interval is

1Inversely proportional to the scale of the map
2Directly proportional to the flatness of ground
3Larger for accurate works
4Larger if the time available is more
