Abstract Due to the high geothermal problems in the rock tunnel of Bulunkou—Gongur hydropower station in Xinjiang，investigations about thermal-stress induced by high temperature is performed firstly；and the reasons of the high temperature in the rock mass around this project are also discussed. It?s found that the heterogeneity of geological formations causes heat flux density to concentrate in the low thermal resistance part，i.e. graphite interlayer，which induceds the high temperature around the tunnel in the rock mass of graphite interlayer. Secondly，construction measures in high temperature are studied，and the ventilation method is reconnended，which is assisted by the spray technology using low temperature water. The support scheme is also suggested for the similar tunnel in the high temperature variation，i.e. using fire and heat-resistant concrete spray or fiber reinforced concrete spray to replace the ordinary concrete lining.

Key words： tunnelling engineering reasons analysis in high temperature tunnel cooling measures lining design in high temperature difference conditions
