Physical Properties: Soil Strength
The soil strength gives a measure of the capacity of a soil mass
to withstand stresses without giving way to those stresses by rupturing
(failing suddenly and quickly) or becoming deformed (failing gradually
by compression). The failure of a soil to withstand gravitational
forces can be seen when a structure settles as its weight exceeds
the soil's bearing strength, when unstable roads and hillslopes
slide downhill, and when earthen dams give way under the pressure
of impounded water. In the context of mine reclamation, soil strength
information is important for construction of: (i) access roads,
(ii) reclaimed hillslopes,
(iii) containment
structures for contaminated material, and (iv) earthen
dams for diversion of water from one watercourse to another,
to capture contaminated water, or to provide water for the reclamation
site. Soil strength tests are conducted to determine a soil's ability
to withstand sudden soil failure and gradual soil compression.
