Abstract Research purposes：With the rapid development of China railway undertakings，a considerable number of tunnel face high rock temperature，high water temperature and other issues．In order to look for the railway tunnel design methods under high temperature environment，and form a complete system to deal with high—temperature rock tunnel design and construction techniques，this paper takes the new railway from Lhasa to Xigaze high temperature rock tunnel design and construction as a backing，surveys and studies the construction and cooling measures for high temperature and heat damage of tunnels，coal mines and deep mines at home and abroad，considering the special climate condition from Lhasa to Xigaze such as high altitude，low air pressures，poor oxygen etc．，chooses Jiwoxiga high temperature rock tunnel as the main study object，conducts a field test trials and effects analysis，accordingly results can provide a theoretical basis．
Research conclusions：For ease of use，heat damage is graded from survey，design and construction stages，and in the plateau region of more than 3 000 metres， heat damage level should improve one grade．Heat damage fortification should be based on non—artificial refrigeration cooling technology，such as ventilation cooling，cold water cooling，spray sprinkler cooling，isolated hot rock，ice cooling etc．，and in combination with other measures to c001．Conclusions made good use of effects in the construction of Lhasa to Xigaze high temperature rock tunnel，resulting in greater economic and social benefits，which can provide references for other similar projects．
