Abstract
Pipe Roof Support systems are increasingly being used in weak ground tunneling although the
design is often only based on experience. The results of an intensive measurement campaign, including settlement measurements ahead of the face, were used to determine a geotechnical model for this pre-support system. The measured ground-support interaction was reproduced utilizing three-dimensional numerical calculations with FLAC-3D. This study confirmed the model created by the in situ data and clarified the influence of the design parameters on both the supporting effect and the ability to control displacements. This enables a more informed decision in the design stage on whether a Pipe Roof System or more cost- and timeconsuming support systems must be used to guarantee the project requirements during construction.
