Based on actual experiences in this field, the paper summarises objectives, constraints and design criteria for monitoring systems for the control of underground excavations in squeezing rock conditions. The design of the monitoring system is a fundamental part of tunnel design, especially for deep tunnels in rock where large convergence is expected after excavation. In these cases the monitoring system must be designed to enable verification of design assumptions as well as measurement of actual loads in each structural component of the primaiy support system and lining for continuous assessment of safety and design. The paper illustrates schematically the application of the principles described.
