عنوان انگلیسی Geosynthetics of Stone Columns- A Review
چکیده انگلیسی مقاله In recent decades, the growth of infrastructure in urban and metropolitan areas has led to a significant increase in the value of land and the lack of suitable places for development. These factors cause the construction industry to look for cheap land for construction; As a result, the building is run on the loose ground against the previous tendency. One of the methods that have been used in recent years in loose deposits and fine soils is stone columns, which are widely used to reduce subsidence and increase the soil bearing capacity of structures such as fluid storage tanks. Embankments, broad foundations, and light structures are used. The use of rock columns as a soil improvement method has been the subject of research by many researchers for the past 40 years. Numerous analytical methods, numerical analyze, and laboratory tests have been performed to investigate the effect of different soil and rock column parameters on the bearing capacity and subsidence of rock columns. One of the most significant research achievements in this field is the idea of reinforcing stone columns with geosynthetic cover, which was proposed more than 25 years ago. During this period, relations have been provided for designing these reinforced stone columns and considering the effect of geosynthetic cover. This paper presents the results of researchers' research on the effect of various parameters on the bearing capacity and subsidence of stone columns.
