ABSTRACT
Earth Pressure Balancing (EPB) TBMs with the use of soil conditioning products has become more and more frequent in the world of tunnelling. The toxicological & ecotoxicological aspects of these products belong to one of the important factors of a well prepared TBM drive.
The right and effective use of soil conditioning additives is not always obvious. An important point for the choice of soil conditioning additives is their possible impact on the surrounding environment. For a complete risk assessment, the emission into ground water during application, the working place concentrations and emissions from the landfilling of the treated soil have to be taken into consideration.
