Q 1) (Solve Any four sub-questions. Each carries 05 marks) (20M)
a) Explain the field procedure to set out a simple circular curve by Rankine’s method of deflection angles.
b) Describe the roles and responsibilities of the Survey of India department.
c) Write a note on Remote Sensing and its applications in Civil Engineering.
d) Draw the format of a 7/12 Abstract and state the data mentioned in it.
e) Explain the working of a handheld GPS receiver.
Q. 2) a) Two tangents intersect at a chainage 1950 m, the deflection angle being 380. Calculate all the necessary data for setting out a curve with a radius of 350 m by Rankine’s method. Take Peg Interval as 30 m. (12M)
b) Two straights AB and BC intersect at a chainage of 2520 m. The deflection angle is 520. It is proposed to insert a circular curve of radius 340 metres between two transition curves of length 85 metres each. Calculate all the elements required to set out the curves. (8M)
Q. 3) a) A downgrade of 2.5% is followed by an upgrade of 3.5%. The RL of the point of intersection is 350 m & its chainage is 1400 m. A vertical curve of 200 m length is to be introduced to connect the two grades. If the peg interval is 20 m, Calculate the elevations of the points on the curve using the tangent correction method. Tabulate the results. (12M)
