CM 3503 Exam 2
____ is defined as the [2] of soil by removal of [3] by means of [4] energy. - ANS-compaction
(delta)Oz - ANS-vertical stress
(T/F) A normally consolidated soil is one that has a present effective pressure (stress) less than
that which the soil has been subjected to in the past. - ANS-False
(T/F) As the compactive effort increases, the optimum moisture content will increase and the
maximum density will increase - ANS-False
(T/F) Immediate settlement is the predominate settlement for a gravel or sandy soil. - ANS-True
(T/F) In-situ methods for determining shear strength of soils include the following: Cone
penetration test, vane shear test, pocket penetrometer, pressure meter, and borehole shear test
- ANS-True
(T/F) Settlement can be caused by deformation of soil particles. - ANS-True
(T/F) Settlement cannot be caused by expulsion of water from voids. - ANS-False
(T/F) The 2-D consolidation test is used to determine the stress strain relationship for soils and
the rate of consolidation - ANS-False
(T/F) The soil can be more than 100 percent saturated. - ANS-False
(T/F) The unit weight of the cut material is equal to the unit weight of the fill material. -
ANS-False
(T/F) the zero air void line (Z.A.V.) is the maximum theoretical density a soil can be compacted
to - ANS-True
(T/F) Water moves naturally from points of low energy to points of high energy. - ANS-False
