Yangtze Three Gorges Technology & Economy Development Co Interview Questions, Process, and Tips

Topographical survey is a detailed study of the natural and man-made features of a piece of land.

• Topographical survey involves mapping out the contours, elevation, and features of the land.

• It helps in determining the suitability of the land for construction projects.

• The survey provides valuable information for designing drainage systems, roads, and buildings.

• Topographical surveys are essential for creating accurate sit...read more

Power house, spillway, headrace tunnels, and diversion tunnels are key components of a hydroelectric project.

• Power house is where electricity is generated using turbines driven by water flow.

• Spillway is used to control the release of water from the reservoir to prevent flooding.

• Headrace tunnels carry water from the reservoir to the power house.

• Diversion tunnels are used to divert water during construction or maintenanc...read more

A load cell is a transducer that converts force into an electrical signal.

• Load cells are commonly used in civil engineering for measuring forces in structures such as bridges and buildings.

• They can also be used in geotechnical applications to monitor soil pressure and stability.

• Load cells come in various types, including strain gauge, hydraulic, and pneumatic.

• They are often calibrated to ensure accurate measurements.

• Ex...read more

A spillway chute is a channel designed to safely convey excess water from a dam or reservoir.

• Spillway chutes are typically lined with concrete to prevent erosion.

• They are designed to handle high flow rates during periods of heavy rainfall or flooding.

• Spillway chutes may include features such as energy dissipators to reduce the velocity of the flowing water.

• Proper maintenance of spillway chutes is essential to ensure th...read more

Dam safety monitoring involves regular inspections, instrumentation, and surveillance to ensure the structural integrity and functionality of dams.

• Regular inspections of the dam structure and surrounding areas are essential to identify any signs of distress or potential issues.

• Instrumentation such as piezometers, inclinometers, and crack gauges are used to monitor factors like water pressure, movement, and structural s...read more

Dam walls are monitored using various instruments for safety purposes.

• Inclinometers are used to measure any movement or deformation in the dam wall.

• Piezometers are used to monitor water pressure within the dam structure.

• Seismometers are used to detect any seismic activity that could affect the dam's stability.

• Crack gauges are used to measure any cracks that may develop in the dam wall.

• Automated monitoring systems can p...read more

There are three classes of rocks: igneous, sedimentary, and metamorphic.

• Igneous rocks are formed from the cooling and solidification of magma or lava, such as granite and basalt.

• Sedimentary rocks are formed from the accumulation and cementation of sediments, such as sandstone and limestone.

• Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure, such as marble and slate.
