In the latest article published on our blog, we discuss the oedometric laboratory test. The oedometric test is used to study the one-dimensional deformation characteristics (zero lateral deformation) of a cohesive soil in the laboratory.
Description and procedure
Inside a steel ring (oedometer), the cylindrical specimen of undisturbed soil test is inserted, and porous septa are placed at the ends to allow water to drain in the vertical direction. A vertical load is applied over a rigid plate, and the vertical settlements of the specimen are measured over time. Purposes The test is carried out on those soils subjected at overloads due to foundations, road embankments etc. In fact, through it the behavior of the soil following an increase in load can be traced.
