Frequently asked Exam Questions with Answers on Soil Mechanics [Geotechnical Engineering] Q. 1. What are the composition of soil? Ans. Soil is a complex body composed of five major components: a. Mineral matter obtained by the disintegration and decomposition of rocks; b. Organic matter, obtained by the decay of plant residues, animal remains and microbial tissues; c. Water, obtained from [...]
Meaning of Seepage: The movement of water through soil is referred to as seepage. The total head at any point of a saturated soil mass, through which water is flowing consists of- (i) Velocity head; (ii) The piezometric head; and (iii) The datum head. Since the velocity through soils is very small, the velocity head is generally neglected. Flow will [...]
Construction of Flow Net for Seepage Analysis! Laplace's Equation: The equation is used in the construction of flow net. Assumptions: 1. Flow is two dimensional. 2. Water and soil are incompressible. 3. Soil is isotropic and homogeneous. 4. The soil is fully saturated. 5. The flow is steady, i.e., flow conditions do not change with time. 6. Darcy's law is [...]
