SURVEYING
T ime: 3 Hours T otal Marks: 70
N ote: Attempt all Sections. If require any missing data; then choose suitably,
SECTION A
1. Attempt all questions in brief. 2 x 7 = 14
a. What are the initial and ?nal sub-cords?
b, What is a 12 cm compass?
c In a map, it is found that two consecutive contour s cross each other. What
would you comment.
(1, How is a chain folded and unfolded?
e. What do you mean by normal tension?
f What is index sketch?
g. What is an azimuth?
SECTION B
2. Attempt any three of the following: 7 x 3 = 21
a. Classify surveying on the basis of instruments used and name all equipments
necessary for the field work involving any one of them.
b, Explain how details can be surveyed by offset from survey lines, Discuss the
relative merits of different types of offsets. Why are short offsets preferred to
long ones.
0. The staff readings for a survey work were as follows:
1,810, 2110, 1,225, 1,455, 0,905, 2435, 2810, 2675 and 1.765.
The level was shifted after the 4?h and 7th readings. The first reading was taken
on a bench mark of R.L. 50,000. rule out a page of level book and enter the
readings:
(i). work out the R,L.s of all stations
(ii). If the staff were held inverted and readings on a ceiling from last
instrument position was 3.500, F ind the R.L, of the ceiling
(iii). Work out the staff readings on the top of 4 pegs at 20 m intervals from the
last station to give an upgrade of l in 100.
d, What is Shift? Prove that a transition curve bisects the shift and that the shift
bisects the transition curve.
e. Why is a curve provided? Derive an expression for an ideal transition curve.
SECTION C
3. Attempt any one part of the following: 7 x 1 = 7
(a) A steel tape was exactly 30 m long at 20?C when supported throughout its
length under a pull of 10 kg, A line measured with this tape under a pull of 15
kg and at a mean temperature of 320C and found to be 780 m long, Cross-
sectional area of the tape = 003 cm2, and its total weight = 0,693 kg. 01 for
steel = 11 x 10?6 perUC and E for the steel = 2.1 x 10 ? kg/cmZ?
(b) What are the sources of error in chaining? What precautions would you take to
guard against them?
Attempt any one part of the following:
7x1=7
(a) The following are the observed fore and back bearings of lines of a closed
traverse. Correct them where necessary for local attraction
Line EB. 33
AB 292015? 11045?
BC 221045? 41045
CD 900 05? 2700 00?
DE 80?35? 261?40?
EA 37000? 216030?
(b) What do you understand by balancing the traverse? Describe any three methods
of adjusting traverse
Attempt any one part of the following: 7 x 1 = 7
(a) What is orientation? What are the methods of orientation? Describe the
methods with sketch.
(b) What do you mean by contour? Describe the characteristics of contour. State
the uses of contour map and contours
Attempt any one part of the following: 7 x 1 = 7
(a) What does the term ?sensitiveness? mean in the context of a bubble? How the
sensitiveness of a bubble is determined?
(b) What do you mean by traversing? Describe various methods of traversing.
Attempt any one part of the following: 7 x 1 = 7
(a) Two straights intersect at angle of 1220. The maximum allowable speed of the
vehicle on the curve is 80 kIn/hr. centrifugal ratio is 1A and the rate of change of
radial acceleration is 30 cm/secz. Calculate the radius of the circular curve and
the length of the transition curve
(b) What is the necessity of transition curve? Describe the different method of
finding out its length.
