Dams and Water Resources Engineering

Soil Mechanics Lab.

Soil mechanics Lab. is offered for third year students. This practical part is to accomplish the theoretical part of Soil Mechanics. In this Lab., students will understand the actual behaviors of soil which are very important for designing engineering structures, for example, dams, bridge foundations, building foundations, and roads. This practical course consists of the following experiments.

Soil properties test:

-  Soil moisture content


Soil classification tests:

- Specific gravity of soil particles.

- Particle-size distribution of a soil (sieving analysis test and hydrometer test).

 - Determination of liquid and plastic limits.


Seepage and permeability tests (determination of the coefficient of permeability):

- Constant head test.

- Variable head test.


Mechanical stabilization:

- Standard and Modified Proctor compaction test (2.5 kg Hammer mass, 4.9 kg hammer mass).


 Shear-strength tests:

- Unconsolidated undrained triaxial test on cohesive soil.

- Direct shear test, including laboratory measurement of pore-water pressure.


Consolidation characteristics (determination of coefficient of consolidation).
