摘要

The limits in the accuracy of the prediction of the geological architecture and rock mass characteristic require an observational approach for the safe and economical construction of tunnels. This especially applies for tunnels in weak ground and/or sensitive environments. It has become common practice to assign a geotechnical engineer to difficult sites to continuously evaluate the geotechnical situation and assist in the routine decision making process. Appropriate site organization and advanced methods for monitoring data evaluation and interpretation are a precondition for efficient work on site. The paper deals with the basic requirements to successfully implement an observational approach, the respective tools for monitoring, and monitoring data evaluations.
