JNTU B.Tech II SURVEYING Previous Question Paper (April/May - 2023 - R15)

What do you mean by plane surveying?

What are the various accessories required in linear measurements?

Write the permanent adjustments in levelling.

Define terms “Contour interval” and “Horizontal equivalent” of contour.

Discuss about embankment and cutting.

State the mid-ordinate rule of area calculation.

List out the major parts of Theodolite.

Explain the Principles of Electronic Theodolite.

What do you understand by Total station?

Differentiate between simple and compound curve.

What do you understand about the offsets in chaining and explain them with neat sketches.

A survey line BAC crosses a river, A and C being on the near and distant banks respectively. Standing at D, a point 50 m measured perpendicularly to AB from A, the bearings of C and B are 320° and 230° respectively, AB being 25 m. Find the width of the river.

The distance between two stations was measured with a 20m chain and found to be 1500 m. The same was measured with a 30 m chain and found to be 1476 m. If the 20 m chain was 5 cm too short, what was the error in the 30 m chain?

What are the errors in the compass survey and write the temporary adjustments of compass survey?

Explain the terms “Local attraction” and “Magnetic declination”.

An instrument was set up at A and the angle of elevation of the top of a tower BC was 26° 15′. The horizontal distance AB, B being the foot of the tower was 715 m. Determine the RL of top of the tower, if the staff reading held on as station P of RL 100.00 m was 2.455 with the telescope horizontal.

Write about the characteristics of contours.

What are the different methods of locating contours and explain any one method among them?

What is Trapezoidal Rule. Derive an expression for it.

The following perpendicular offsets were taken at 5 m intervals from a traverse line to an irregular boundary line 2.10; 3.15; 4.50; 3.60; 4.58; 7.85; 6.45; 4.65; 3.14 m. Compute the area enclosed between the traverse line and the irregular boundary from the first to the last offset.

A straight railway embankment is made on a ground having a transverse slope of 1 in 8. The formation width of the embankment is 30m. And the side slopes are 1.5H to 1 V. At three sections 50m apart, the heights of the bank, at the center of the formation levels are 10m, 15m and 18m. Compute volume of earthwork involved in the embankment.

List the general methods of calculating area with one example.

Describe the method of repetition for measurement of horizontal angle by theodolite.

Explain in detail, the procedure of two theodolite method of deflection angle for setting out a circular curve in the field.

Give a list of the permanent adjustments of a transit theodolite and state the object of each of the adjustment. Describe how you would make the Trunnion axis perpendicular to the vertical axis.

Explain why transit rule is more suitable than Bowditch rule for adjustment of a closed theodolite traverse.

Derive an expression for the horizontal distance of a vertical staff from a tacheometer, if the line of sight is inclined.

When do you prefer simple curves and compound curves? Explain with neat sketches.

Explain the principle of working of total station and its utility in Civil Engineering.

Discuss about various applications of GPS in Civil Engineering.
