failure and....
Answer: Sliding
◉ The condition shown below in which the soil around the
perimeter of the foundation is pushing up on the foundation edges is
called heave. Pic in Soils and Foundations HW 1
,Answer: True
◉ Frost depth is a phenomena in which the soil either gains or loses
moisture which in turn leads to expansive or subsidence in the
volume of the soil.
Answer: False

between the summer and winter periods is most nearly the
definition of....
Answer: Depth of Seasonal Moisture Variation

tension reinforcement? Pic in Soils and Foundations HW 2
Answer: Vertical Bars - B
◉ An auger-cast pile is an example of a shallow foundation.
Answer: False
◉ All conditions being equal, post-tensioned foundation are
generally cheaper that conventionally reinforced stiffened slab-on-
grade foundations.
Answer: True

the perimeter of the foundation) in a post-tensioned stiffened slab-
on-grade foundation is most nearly to.... Pic in Soils and Foundations
