To the Limits of Shotcrete Liningsby Rudolf Pöttler, Kling Consult GmbH, Krumbach, Germany,
Abstract: In the 1950s for the first time shotcrete was used because an essential support measure to guarantee the stability of an underground opening in Austria, Detzelhofer (1). Since that time the use of shotcrete has proved to be one of the most flexible and effective support measures in rock and soft ground tunnelling. Depending on the geological boundary conditions and on the ground water situation the load bearing behaviour of the shotcrete lining can be divided into 3 characteristic cases, being considerable different in terms of dimensioning of the lining, stresses in the lining and necessity of the lining.
