Experimental Study on Load-Settlement Behaviour of Granular Stone Column in Expansive Soil
In today’s construction industry as land reclamation is increasing rapidly so ground improvement has become necessity. Ground improvement is carried out by increasing vibration, structural fill or reinforcement, vegetation, admixtures, etc. out of all the methods, the stone column technique is a very effective method of improving the strength parameters of soil like bearing capacity and reducing settlement, particularly, for the construction of flexible structures, such as road embankments, oil storage tanks on soft soils. It offers a very economical and sustainable alternative to piling and deep foundation. The model test was performed on untreated soil and treated soil with 40 mm, 60 mm, 80 mm diameter stone column. The investigation focused on the influence of diameter of granular stone column. The tests were conducted on granular stone column having l/d ratio equal to 10. From the studies, the performance of smaller diameter stone column is superior to that of bigger diameter stone column. Due to its higher modulus of elasticity than that of soil, it absorbs more load than soil and reduces overall settlement.
