    One of the efficient methods to improve soil behavior is the use of stone columns. Due to the high volume of studies on the performance of single Stone columns, in this study, we will seek to investigate the performance of group Stone columns in improving the behavior of sandy soils. Sandy soils, especially in coastal areas, due to the lean mechanical properties of the soil, have always been considered an unsuitable soil sample in the design and the need for improvement in this type of soil is urgently needed. Therefore, in this article, by using stone columns as a group, we will seek to improve the behavior of sandy soil. How to arrange the stone columns (square, triangular arrangement) and the diameter of the stone columns (60, 80 and 120 mm) are the main variables in this article. In all models, the length-to-diameter ratio is considered equal to 5. The load-carrying capacity and soil settlement have been investigated for different modes of stone column arrangement in the laboratory environment as superimposed load. The results obtained from the article show that the arrangement of the stone column in a triangular and square shape can increase the soil load carrying capacity by 31.8 and 37.5%, respectively. This incremental trend is more noticeable in the square arrangement. Also, based on other results of this article, it was observed that by increasing the diameter column parameter and increasing the diameter equivalent of the stone column group, we will see an improvement in the performance of the stone column group in increasing the sandy soil load-carrying capacity.
