Abstract
Vallarpadam ICTT Port in the state of Kerala was connected with NH-47 by 17.20 km long four-lane highway. Starting from the junction with NH-47, the first 8.40 km length of the project road was on land area. The rest of the project corridor was routed across reclaimed land and the last part of the road was in island of port area. Deep soft clay deposits were found along the project road. In the land area of project stretch, stone column had been adopted for the foundations of RCC retaining wall and box underpass structure as an alternative to pile foundations. The details of foundation adopted, design involving evaluation of load bearing capacity of stone columns-treated soft ground for the retaining wall and underpass structures, and results of load tests on stone columns are provided here in this paper. Details of machinery used, procedures adopted in the installation of vibratory stone columns, and different field controls adopted to ensure the proper formation of stone columns are presented here.
