10+ Megha Engineering & Infrastructures Interview Questions and Answers

The volume of EV2 subgrade and blanket material can be calculated based on the dimensions and density of the materials.

• Calculate the volume by multiplying the area of the subgrade or blanket material by the thickness

• Consider the density of the material to convert volume to weight if needed

• For example, if the area of the subgrade is 100 square meters and the thickness is 0.5 meters, the volume would be 50 cubic meters

A civil engineer is a professional who designs, constructs, and maintains the built environment.

• Civil engineers design and oversee the construction of infrastructure such as roads, bridges, buildings, and water systems.

• They use principles of mathematics, physics, and engineering to ensure that structures are safe, efficient, and sustainable.

• Civil engineers also play a role in environmental protection and disaster response, as they are responsible for designing and implementin...read more

CBR test is a laboratory test used to determine the strength of a soil sample.

• CBR stands for California Bearing Ratio.

• It is a penetration test that measures the load-bearing capacity of a soil sample.

• The test involves compacting the soil sample in a mold and subjecting it to a standard load.

• The ratio of the required force to penetrate the soil to the force required for a standard material is calculated.

• CBR values range from 0 to 100, with higher values indicating stronger and...read more

PSC girder is a type of bridge girder made of pre-stressed concrete and post-tensioning is a method of reinforcing concrete.

• PSC girder stands for Pre-Stressed Concrete girder which is a type of bridge girder made of concrete that is pre-stressed with tensioning cables.

• Post-tensioning is a method of reinforcing concrete by placing steel tendons in the concrete and then applying tension to the tendons after the concrete has hardened.

• This method helps to reduce the amount of con...read more

Chemical test in steel is a process of analyzing the composition of steel to determine its chemical properties.

• Chemical tests are used to determine the amount of carbon, sulfur, phosphorus, and other elements in steel.

• These tests are important for ensuring that the steel meets the required specifications for its intended use.

• One common chemical test is the spectrometric analysis, which uses a spectrometer to measure the amount of each element in the steel.

• Another test is the ...read more

GSA, MDD, and CBR tests are procedures used in civil engineering to assess the strength and stability of materials.

• GSA (Gradation, Shape, and Angularity) test is used to evaluate the particle size distribution of aggregates.

• MDD (Maximum Dry Density) test determines the maximum density achievable for a soil sample at a specific moisture content.

• CBR (California Bearing Ratio) test measures the strength of a soil sample by comparing its bearing capacity to a standard crushed roc...read more

Major bridges are larger and carry more traffic than minor bridges.

• Major bridges are typically longer and wider than minor bridges.

• Major bridges are designed to carry heavy loads and high volumes of traffic.

• Examples of major bridges include the Golden Gate Bridge and the Brooklyn Bridge.

• Minor bridges are typically shorter and narrower than major bridges.

• Minor bridges are designed to carry lighter loads and lower volumes of traffic.

• Examples of minor bridges include pedestrian ...read more

GSB layer is a granular sub-base layer used in road construction to provide stability and support.

• GSB layer stands for Granular Sub-Base layer.

• It is typically made up of compacted aggregates like crushed stone or gravel.

• The purpose of the GSB layer is to provide a stable and solid foundation for the road pavement.

• It helps in distributing the load from the pavement to the underlying soil.

• The GSB layer also helps in preventing the upward movement of water from the subgrade.

• It i...read more

There are various types of bed testing, including durability testing, stability testing, and comfort testing.

• Durability testing involves assessing the bed's ability to withstand wear and tear over time.

• Stability testing checks the bed's ability to support weight and movement without tipping or collapsing.

• Comfort testing evaluates the bed's overall comfort level, including factors like firmness and pressure relief.

Limit cu and cc refer to the maximum allowable values of undrained shear strength and compression index in soil mechanics.

• Limit cu is the maximum undrained shear strength of soil, typically ranging from 0.5 to 10 ksf.

• Limit cc is the maximum compression index of soil, usually between 0.1 to 1.0.

• These limits are important in geotechnical engineering for determining the stability and settlement characteristics of soil.

• For example, cohesive soils with cu values above the limit ar...read more

There are several types of pile load tests, including static load test, dynamic load test, and integrity test.

• Static load test involves applying a static load to the pile and measuring the response.

• Dynamic load test involves using a hammer to strike the pile and measuring the response.

• Integrity test involves using sonic or ultrasonic waves to test the integrity of the pile.

• Other types of pile load tests include statnamic load test and bi-directional load test.
