Experimental Design Of Stone Columns By Small-scale Unit Cell Modelling: A Review

This paper presents review of the experimental design of small-scale single stone column that adopts the unit cell concept. Materials and methods used in experiments along with their effects and implication have been appraised. The reviewed cases showed that clayey soils were often considered as host ground material. Steel cylindrical tanks were used with diameters ranging from 15 to 60 cm and heights ranging from 20 to 120 cm. For this scale of experiment, stone size of 2 to 10 mm have been selected. Plates load test can be carried out on the entire tank or stone column. The load has been imposed at constant displacement rate of 1 to 1.25 mm/min in order to simulate the stage immediately after construction. The review shows that remoulding and replacement have been often practised for the construction of the host ground and the stone column, respectively.
