Abstract
Tunnel construction in difficult geological conditions requires special attention in order to sat-
isfy safety demands and economical requirements. In particular in heterogeneous ground the prediction of the behavior of the rock mass is essential to be able to adjust excavation and support in time. Very rarely is the required know-how to cope with geotechnical problems available on site. The Internet allows a nearly real time site assistance by experts located somewhere in the world. Relevant data are transferred via Internet, and the data analyzed with special tools by experts. The behavior of the tunnel is analyzed on its “normality”,
predictions of the future development of displacements and the geotechnical situation ahead of the face (short term prediction) are made. The result of the analyses and recommendations are communicated by Internet or via phone in urgent cases within a few minutes to a few hours. The intervals of data transmission and duration of involvement of the expert(s) is adjusted to the needs of the site. The paper demonstrates the possibilities of this type of online expertise with the help of selected case histories.
