Abstract

In Civil Engineering practice, soil is used as a construction material for Dams, Canals, Roads, Railways, and Embankments etc. In most of these scenarios local soils are to be used as they naturally occur, which can hardly be described as stable soil and needs improvement in one respect or another. Due to rapid urbanization, it has become obvious to utilize even the poorest of sites under consideration. This could be achieved either by providing specially designed foundations or by improving the soil at site. So, being easier and cost effective, especially in the long term, soil improvement at site is necessary. This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime –Soil (CL-S) rigid stone columns in soft soils. The unit cell idealization is used for construction of composite specimens to evaluate the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar). Experiments were carried out on both end bearing and floating columns. Load was applied over entire area of the specimens to find the stiffness of the improved ground. Based on the results, it was concluded that CL-S columns increase the load carrying capacity and reduce the settlement of soft soils. In addition, the results show the influence of model size on the stiffness of the specimens which means that the load carrying capacity decreases by increasing the size of the model. However, for specimens containing columns with diameters greater than 100 mm, the variation of stiffness becomes negligible and hence the results can be used to extrapolate and predict the full size behavior of these columns. The experimental results were compared with results reported in the literature for conventional stone columns.
