Design of a tunnel lining is complex task. The tunnel lining structure works in close interaction with the surrounding rock mass. The value of the load depends on geotechnical circumstances, primary lining, shape and size of opening, construction technology and as well on the temperature distribution in a lining that is determined by climatic conditions. The article deals with the temperatures in the tunnel lining that are brought about by air temperature changes in tunnel space and a constant temperature inside the rock mass. This problem is solved making use of temperature records in tunnel, on the inner and outer surface of the tunnel lining and in rock mass measured at a motorway Tunnel Klimkovice. These records are analyzed and submit to FE model of the tunnel lining so that the lining temperature state is converted for a lining stress state.
