The main purpose of consolidation tests is to obtain soil data which is used in predicting the rate and amount of settlement of structures founded on clay. Jaafar Mohammed E-mail: jaafar.brifkani@uod.ac jaafar.mohammed.st@vsb.cz Introduction Consolidation is a process by which soils decrease in volume. ⇒ Significant in saturated clayey soils. Some Definitions Settlement: change in elevation Compression: change in thickness. The boundary is a free surface. Difference between Compaction and Consolidation of Soil. Consolidation refers to the compression o settlement that soil undergo As response of placing loads on to the ground These loads produce corresponding increases in the vertical effective stress Consolidation is a time- dependent process in some soils it may take long time ( 100 years ? ) The seepage of water from the soil during consolidation may be represented by means of a head diagram of the type shown in Fig. This is one of over 2,200 courses on OCW. Therefore it decreases its volume with time. The test is conducted to determine the settlement due to primary consolidation. Porous stone.
