The Effect Of Fine Particle Migration On Void Ratio Of Gap Graded Soil

Soil is exposed to the migration of fine particles in some cases because of some conditions, including excavation and the presence of a level of groundwater, which is equal to the level of soil in this case and because of the existence of this water leakage, which would work on the migration of fine particles in the soil. This migration of fine particles will change the structure of the soil and change its properties. In this study, we will know the change in the properties of the fouling soil due to the migration of fine particles and four types of soil. The first type does not contain fine particles , and the second type, the third and the fourth contains 10, 20 , 30% granules respectively, and tests were carried out for these soils (Atterberg limits, sieve analysis, specific gravity , shear resistance, permeability, modified Procter, consolidation). A model was created to simulate the reality of soil exposed to excavations. Three levels were selected in the model to compare the results of each of the four soils under study. The total number of models (24) model, through laboratory work obtained the initial and final voids ratio before and after aft the initial and final voids ratio er the particles migration. After these tests, it was found that the migration of granules clearly affects the increase in the voids ratio.
