The process of consolidation Essay Example

The process of consolidation

 Another load was placed on the sample and the aforementioned process repeated. The load was reduced bit by bit after a significant application. A load increment ratio of 0.5 was used to establish an appropriate framework for the description of a relationship between effective stress and void ratio. As the test continued, the water level in the cell was checked from time to time to ensure that it stayed on the top of the porous stone. After the completion of the test, the soil sample was removed followed by recording thickness and water content details. Discussion and conclusionThe lab was successful in meeting the major objective the magnitude and rate of volume decrease witnessed by a soil specimen when subjected to load. This was made possible by determining the void ratio in relation to the effective stress imposed by the load. As seen in the results, the void ratio test reduced from 0.506 to 0.3617 before and after a test. This insinuates the influence of water expelled out of the void after water was expelled out by the impact of a load. Initially, the voids were filled with water but due to the addition of the load, a decrease in volume occurs hence confirming the consolidation process. In essence, the use of oedometer test carried out on the saturated soil specimen helps in determining the consolidation and swelling perimeters of the soil determined. This shows the usefulness of consolidation test in geotechnical laboratory testing. Even though the experiment was successful, possible sources of error might have contributed to limitations between real-life applications and the experimental test results of the consolidation test. This could be because of errors in estimating a rate of settlement, whereby the practical applications normally have shorter settling time than that evident in experimental test results. This deviation could be attributed to sampling size since the sample size was not big enough compared to the soil fabric and its characteristic deep effects on drainage conditions.
