Regular Theory Examination (Odd Sem - III),2016-17
SURVEYING - I
Time : 3 Hours Max. Marks : 100
Section - A
Attempt all parts. Each part carries equal marks.
(10XZ=20)
1. Correction due to refraction is given by
a) 0.0112 D2 - b) 0.0673 D2
0) 0.0785 D2 (1) 0.0012 D2
2. What do you mean by working from ?Whole to
part??
3. What is levelling and why it is important in survey
work?
4. Write relationship between level line and horizontal
line.
5. For an open traverse, which is correct -
a) 2 latitude = 0 b) Both (i) & (ii)
0) Z departure = 0 d) none of the above

What is magnetic declination?
What is the basic importance of provision of curves
in highway?
8. Explain the elements of simple curve, with neat
sketch.
9. What is triangulation?
10. What is resection?
Section - B
Attempt any three questions. (3X10=30)
l. The distance measured between two points on a
sloping ground is 450 m. Find the correction to be
applied and horizontal distance if -
a) The angle ofslope is 10?
b) The slope is in 1 in 5
c) The difference in elevation between two point
is 45 m.
2. A closed traverse has the following lengths and
bearings:
Line Length (M) Bearing
AB 200.0 ROUGHLYEAST
BC 98.0 178?
CD NOT REQUIRED 270?
DA 86.4 1?
NCE-303
The length CD could not be measured due to some
obstruction to chaining. The bearing of AB could
not be taken, as station A is badly affected by local
attraction ?nd the exact bearing of the side AB and
calculate length C?
Explain the two point problem of plane tabling with
a neat sketch?
A road 8 m wide is to de?ect through an angle of
60? with the centre line radius of 300 m, the
chainage of intersection points being 3605.0 m. a
transition curve is to be used at each end of circular
curve of such a length that rate of gain of radial
acceleration is 0.5 m/s3. When speed is 50 kmph.
Find out
a) Length of transition curve.
b) Superelevation.
c) Chainage of all junction points.
A 30 m long steel tape is supported at the ends. Find
the normal tension for the tape with the following
details :
Cross section of the tape = 4 mmz, unit weight of
the tape material = 78600 n/m3, E = 2 x 1011 n/mz,
the pull which the tape is standardized is 100 n?

Section - C
Attempt any ?ve questions. (5X10=50)
Explain curvature and refraction correction is in levelling,
the eye of an observer is 7.5 m above sea level and he
was able to see a light house 50 m high just above the
horizontal. F ind the distance between observer and
lighthouse?
De?ne a contour. Discuss the method of contouring.
What are the various method of interpolating contour?
State the stability of each one of them.
What are the different check inclosed traverse and open
traverse?
State the 3-point problem, explain how it is solved by the
graphical method?
What are the essential requirements of a transition curve,
derive an expression for an ideal transition curve?
The apex distance of a 3? circular curve is 82. 45
determine the de?ection angle, tangent l??vgth an(1 1mg
. of long chord?
Explain the indirect method of contouring, wh?attare the
advantages and disadvantages of these method?
