Abstract

Granular piles, which consist of granular materials, are widely used as a soil improvement technique for increasing the bearing capacity of soft soil and reducing the settlement. In this study laboratory tests were conducted to find out the effectiveness of granular materials and the granular piles constructed to improve the soft soil conditions. To overcome the limitations of the conventional foundation systems, the development of modern foundation practices, namely ground improvement techniques have been proved to be viable both technically and economically. Installing granular pile as a ground improvement technique has been adopted as one of the most cost effective and efficient methods for its ability in increasing the bearing capacity and reducing the settlement. This study mainly deals with the performance of the granular materials used for the construction installed in soft ground. Reconstitute clay is prepared into a plastic cylindrical mold. For investigating the performance of the granular materials, sand piles were constructed of coarse sand and the stone columns were constructed by stone chips and sand mixing in equal ratio. The load tests were done individually for all the cases. The results found from the study indicate that load bearing capacity of soft ground can be increased significantly by installing sand pile and stone column. The laboratory test results show that the load carrying capacity of the improved ground is averagely 5.53 times more for the ground treated by sand column and averagely 6.09 times more for the ground treated by stone column, in comparing with the untreated ground. From this study, it can be concluded that although the combined using of sand and gravel in equal ratio gives slightly higher improvement, both sand and gravel can be effectively used for construction of granular piles.
