Abstract

This paper describes the construction of four large tanks on poor soil conditions consisting of hydraulic fill placed over estuarine silt in Dublin port. The limited differential settlement that could be tolerated by the tanks required that they could not be placed on the existing ground. The optimum solution was found to be ground treatment using vibro-replacement with the formation of stone columns and compaction of the fill. The paper describes the design method used and the control tests. The predicted settlements are compared with settlement readings of the tanks following construction. These show that the chosen solution has performed well and satisfied the design requirements.

Performance of LPG Storage Tanks on Ground Improved by Stone Columns

This paper describes the construction of four large tanks on poor soil conditions consisting of hydraulic fill placed over estuarine silt in Dublin port.

The paper describes the design method used and the control tests. The predicted settlements are compared with settlement readings of the tanks following construction.
