| description | Sand or stone columns are considered one of the efficient methods ofimproving soft clayey soils. They are cheap, easy to use, and results inincreasing the bearing capacity of the soil and decreasing its compressibility.In this research, a series of laboratory tests were performed using small scalecolumns (Dia. = 38 mm, Depth = 180 mm) inserted in a soft claylayer which was prepared inside steel containers. Different amounts of limeand / or cement were used to stabilize the stone columns to increase itsefficiency. Loading tests were performed on each column in order todetermine its max. bearing capacity, the efficiency of each additive wasdetermined by comparing the results obtained of treated to untreatedcolumns (qt / qu). The results were (2.7) for soils treated with crushed stoneonly, and (4, 5) for soils treated with crushed stone stabilized with (5%) and(10%) lime respectively. The results also showed (3.5, 4) for soils treatedwith crushed stone stabilized with (5%) and (10%) cement respectively. Theresults of stabilizing stone columns with lime and cement showed that(qt / qu) were (3.3, 3.7) for soils treated with crushed stone stabilized with(2.5% lime + 2.5% cement) and (5% lime + 5% cement) respectively. |
