The Experimental Analysis Of The Effect Of Geotextile Reinforcement Of Cohesive Soil On The Settlement And Bearing Capacity

Abstract

The properties of the soils in terms of engineering must be identified for the design of buildings and foundations to be constructed in areas where soft clay or loose sand ground conditions predominate. The engineering properties of different soils diversify in a broad range based on the sort of the ground in addition to the terrain conditions like the degree of compaction, water content, consolidation pressure, loading, and drainage conditions. Grounds may not perpetually hold the desired properties. Thanks to the structures to be built on the grounds, excessive settlements or collapses can happen because of inadequate ground bearing capacity. In order to reinforce the weaknesses of the soils, either the application of a deep foundation should be employed, or a proper improvement method should be applied to the foundation ground.In the study, the effect of the reinforcement of the geotextile, which has become widespread, on the clay ground was examined. Experiments have been conducted to identify the index properties, settlement, and sliding resistance parameters of soils on Süleyman Demirel University Soil Mechanics Laboratory on clay samples from the provinces of İzmir and İstanbul. Following the identification of the settlement and sliding values, the geotextile was added, and its effect on the settlement and bearing strength values was analyzed. Experiments were conducted by placing single-layered and double-layered geotextile in the samples with the values of optimum water content, the water content 10% more than the optimum value, and the water content 10% less than the optimum value.The results achieved after laboratory experiments are displayed with graphics and compared with each other.
