Their significance is essential and any unnecessary closures or limitation of traffic should be excluded. The tunnel design must be safe and satisfy stringent requirements on serviceability and durability. The tunnel design \u00EDs based on many parameters, which are unreliable and exhibit large statistical scatter. The design of tunnel linings is based on the data obtained during the driving of the exploratory drift o\u0159 even during the driving of the tunnel \u00EDtself. The objective of the project is to acquire systematically the data for tunnel lining design from ineasuremenfs executed during the tunnel construction. The two kinds of measurements are proposed. The first one covers measurement during driving the tunnel. Measurements of stresses using speci\u00E1l hydraulic cel\u00ED\u0161 will be continuously taken and Electronically recorded.
