ABSTRACT
Eka Chemical has an industrial site located at Göta River in Sweden. The soil consists of clay to about 40 -60 meters depth. The slope stability was insufficient at a shoreline of about 900 meters length. It was necessary to secure the slopes. The stability improvement was designed as a support filling in the river and soil reinforcement with lime columns along the shore.
During installation of the lime columns continuos supervision of pore water pressure and horizontal soil movements were necessary. At the main part of the installation the measuring results were registered automatically. The primary intention was guidance during the installation to prevent slope failure caused by installation. At the same time a large amount of measuring results were registered.
This Paper discusses the results of the observations with diagrams and examples, showing the correlation between installation of lime columns, the increase of pore pressure and soil movements. However no theoretical analysis of the correlation have yet been made.
