Learning Objectives

• Learn how dynamic tests are used to evaluate foundation support characteristics under repeated loadings such as a drop forge, traffic, or earthquake; and the associated risks of liquefaction.

• Learn about correlations between index and structural properties showing the probable range of test values and relation of parameters.

• Learn how grain-size analyses may be applied to seepage and drainage problems.

• Learn how permeability of fine-grained soils (undisturbed or compacted) generally is computed from consolidation test data or by direct measurement on consolidation or triaxial shear specimens.

• Learn how one-dimensional consolidation tests with complete lateral confinement are used to determine total compression of fine-grained soil under an applied load.

• Learn how to estimate preconsolidation pressure using graphical determination from a semi-logarithmic pressure-void ratio curve.

• Learn about the coefficient of consolidation.

• Learn how the shear strength of soil is required for the analysis of foundation and earthwork stability problems.

• Learn about the different types of shear tests.

• Learn about direct shear tests.

• Learn about unconfined compression tests.

• Learn about triaxial compression tests.

• Learn about the Unconsolidated-Undrained (UU) or Quick (Q) triaxial compression test.

• Learn about the Consolidated-Undrained (CU) or R triaxial compression test.

• Learn about the Consolidated-Drained (CD) or S triaxial compression test.
