| Abstract: | The Sangzhuling tunnel in the IJiasa-Iinzhi section of the newly-built Sichuan-Tibet railway passes through the granite strata. It encounters high g*ound temperature successively in the construction process due to large burial depth, active geological structure and high geothermal energy. Based on the successful construction experience of the high temperature section of Sangzhuling tunnel, various construction countermeasures of the tunnels on plateau and of high earth temperature are studied and discussed in this paper, which can he used as reference for similar projects. |
