SOIL MECHANICS TEST WITH
GUARANTEED ACCURATE ANSWERS
Darcy's Equation - ACCURATE ANSWER✅✅Used to calculate the volume of
water flowing through soil per unit time
Flow Nets - ACCURATE ANSWER✅✅- Graphically show the total head or
energy lost if water flows through a porous media
- Graphical solution of Laplace equation
Laplace Equation - ACCURATE ANSWER✅✅Represents the energy loss (total
head loss) through any resistive media (i.e. soil)
Flow Net Grids - ACCURATE ANSWER✅✅Have:
- Flow lines
- Equipotential Lines
Flow Lines - ACCURATE ANSWER✅✅- Represent the average flow path of a
water particle (parallel to the movement of water)
- Impervious surfaces
Equipotential Lines - ACCURATE ANSWER✅✅Lines of constant total head
Flow Paths - ACCURATE ANSWER✅✅Spaces between flow lines
Drop - ACCURATE ANSWER✅✅- Each square in the flow net
, - drop i.e. drop in total head
Equipotential Line at Maximum Total Head - ACCURATE ANSWER✅✅The
surfaces where water enters the soil
Equipotential Line at Minimum Total Head - ACCURATE ANSWER✅✅The
surfaces where water leaves the soil
Distance Between Equipotential Lines - ACCURATE ANSWER✅✅- Represents
a drop or loss in total head
- The distance over which ∆hT -drop is lost
Piping or Quick Condition - ACCURATE ANSWER✅✅- Phenomenon where
seeping water progressively erodes or washes away soil particles creating voids
- Cause of most deaths than all other civil engineering failures combined
- Critical place is where water exits the soil
- Develops at the exit of water from soils if the hydraulic gradient exiting is equal
to or greater than the critical gradient
Liquefaction - ACCURATE ANSWER✅✅The loss of strength in saturated,
cohensionless soils due to the build-up of pore water pressure during dynamic
loading
Critical Gradient - ACCURATE ANSWER✅✅Function of buoyant unit weight
or the void ratio and the specific gravity of the soil
Effective stress (sigma') - ACCURATE ANSWER✅✅- Intergranular or contact
pressure between soil particles
