Abstract
This paper discusses a consistent procedure to quantify geological, geotechnical
and economic risk in tunneling. For an underground excavation a sound rock mass
model and a systematic and quantitative rock mass characterization has to be
developed. After defining key parameters, Rock Mass Types are determined and
combined with influencing factors to obtain the behavior of the rock mass after
excavation. A support and excavation concept is assigned to each Behavior Type,
which allows an estimate of time requirement and costs. The probabilistic
processing of distributed input data allows the determination of probability
distributions for time and costs of a tunnel excavation based on the geotechnical risk
and the variation of time and costs of different Excavation Classes.
