Yolax Infranergy Interview Questions and Answers

Tests conducted during earthworks include compaction tests, moisture content tests, and sieve analysis.

• Compaction tests measure the density of the soil after compaction, ensuring it meets specified requirements.

• Moisture content tests determine the amount of water present in the soil, which affects its compaction and stability.

• Sieve analysis is used to determine the particle size distribution of the soil, which can impa...read more

The degree of curve of a railway line can be found using the radius of the curve and the length of the chord.

• Calculate the central angle of the curve using the chord length and radius.

• Convert the central angle to degrees to determine the degree of curve.

• Degree of curve = (360 * central angle) / (2 * pi).

Sleeper density refers to the number of sleepers (wooden or concrete supports for railway tracks) per unit length on a main line.

• Sleeper density can vary depending on the type of track (main line, branch line, high-speed line, etc.)

• Typically, main lines have a higher sleeper density compared to branch lines to support heavier traffic.

• For example, a main line may have a sleeper density of 20 sleepers per 60 feet of trac
