FAQs on Handwritten Notes: Seepage Pressure & Critical Hydraulic Gradient - Soil Mechanics - Civil Engineering (CE)

1. What is seepage pressure in civil engineering?
Ans. Seepage pressure in civil engineering refers to the pressure exerted by water as it flows through soil or rock. It is the force per unit area acting on the soil due to the flow of water.
2. How does seepage pressure affect the stability of structures?
Ans. Seepage pressure can cause instability in structures by increasing the pore water pressure in the soil, reducing the effective stress, and potentially leading to soil liquefaction or slope failure.
3. What is the critical hydraulic gradient in civil engineering?
Ans. The critical hydraulic gradient is the slope of a water table at which seepage forces equal the effective stress of the soil. Beyond this gradient, seepage pressure can cause instability in the soil.
4. How can seepage pressure be managed in civil engineering projects?
Ans. Seepage pressure can be managed by using drainage systems, such as weep holes, French drains, or geotextiles, to control the flow of water and reduce the build-up of pressure in the soil.
5. What are some common methods used to measure seepage pressure in civil engineering?
Ans. Common methods used to measure seepage pressure include piezometers, standpipes, and observation wells, which provide data on pore water pressure and help engineers monitor potential risks to structures.
