“…This differs from 38 the 42 and is also significantly influenced by the thickness of the blanket material forming the column and the strength of the surrounding soil (12). In theory, both are consistent with this (Barksdale and Bachus, 1983, Han and Ye 1991, Aslani and J. Nazariafshar 2021) (13)(14)(15). Some research and studies have turned to encase the stone column in geogrid or another high-tension material to counteract the weakness caused by a flaw in the soil around it.…”

The usage of stone columns is one of the best ways to accentuate the ground. minimize settlement and increase the soil's carrying capacity. In this study, stone columns with complete geogrid reinforcement built of recycled concrete aggregates were utilized. Soft clay soils have been strengthened in a variety of methods. The results indicated that the use of stone columns made of recycled concrete aggregates fully reinforced with geogrid resulted in a significant improvement in the BC of soils. Compared to natural soil, the use of stone and double columns reinforced with a geogrid network improved the BC of the soil by 9% with an increase in the percentage of improvement when using other patterns.
