Abstract (2. Language): 
Soft clay soils there in many coastal areas. These soils generally have high compressibility and don't provide required bearing capacity. Various techniques are used to improve these soils. Among existing techniques, stone columns are known as quick and inexpensive method. The benefits of columns are: increasing the bearing capacity, reduction the total and differential settlements, acceleration the consolidation time and decreasing the liquefaction potential. Due to the poor performance of columns in very soft soils such as peat, various methods have been developed to increase the efficiency of the columns such as vertical encased, horizontal reinforced and construction of reinforced and unreinforced sand bed over the stone columns. This article presents a review of these existing techniques and evaluated the effectiveness of each of these methods.
