摘要
简要介绍了位于青藏高原大坂山隧道的工程概况及特点、高海拔高寒地区隧道的主要施工原则及施工方法;阐述了防排水、防寒保温、机械配套、人员防护、低温混凝施工等关键技术;提出了高海拔、高寒隧道施工的注意事项。
In connection with the special climate characteristics,engineering geology and hydraulic geology of Dabansha,some new theories,new technologies and new materials are comprehensively employed in the construction of high elevation tunnel in cold weather.Some technologies are suitable for the tunnel construction with high elevation and cold condition,such as comprehensive waterproof and drainage,prevention of frost damage and heat preservation,and the construction equipment mechanization,are researched and developed with the comprehensive usage of new theory,new method,new technology and new materials.Based on of large amount of researches and experiments,some new technologies have been successfully applied to similar engineerings in China to solve many technical difficulties.
