| Description
| - The most important element in physical modelling consists of the instrumentation, the proper design and installation of which is essential in providing accurate results for evaluating the phenomenon under investigation. However, %22in situ%22 conditions have the disadvantages of inaccessibility and the impossibility of repairing or replacing the sensors. Therefore, in any long-term experiment conducted under extreme conditions, a high degree of sensor thermal resistibility is required. The physical model of the influence of thermal load upon underground structure linings contained over 250 sensors for measuring temperature, stress, deformation and strain and was loaded with temperature up to 90°C over three years; some of the sensors failed during the course of the experiment. Moreover, it was observed that measured values depend on temperature despite this information not being disclosed in the equipment certification. Therefore, tests were performed to determine temperature-dependent calibration curves. Recommendations and procedures for the instrumentation of physical models subjected to long-term temperature loading were determined based on experience gained from the experiment. Recommendations concern the installation of appropriate types of sensors and procedures prior to the construction of such %22in-situ%22 physical models.
