Monitoring of soil deformations induced by deep mixing using an FME-based data analysis tool

A vast land reclamation project is under construction in Sweden, within a bay of the Baltic Sea. To enclose the area from the bay, a 600 m long rubble mound of crushed rock founded on deep mixing is constructed. The area has previously been prone to slides with its very soft clay. This paper focuses...

Summary:A vast land reclamation project is under construction in Sweden, within a bay of the Baltic Sea. To enclose the area from the bay, a 600 m long rubble mound of crushed rock founded on deep mixing is constructed. The area has previously been prone to slides with its very soft clay. This paper focuses on the design and execution of the rubble mound in the western land connection, where the rubble mound serves as a temporary working platform. A rigorous control program was developed to ensure a safe work progress. To process all the data and facilitate analysis an FME-based tool was developed providing instant feedback for the designer. This paper describes the design process and the monitoring during execution as well as the measures taken when deformations exceeded alarm values. The paper also presents measured soil displacement and provides practical tips for future deep mixing projects where deformations are of concern.
