摘要
青藏铁路昆仑山隧道属典型高原冻土隧道 ,高原冻土、高寒缺氧、低气压、低氧分压等客观因素给隧道修建带来许多困难。文章从机械配套、通风、湿喷混凝土、仰拱作业桥、防排水结构、隔热保温层、低温早强耐久混凝土、供氧及健康监测等方面介绍了该隧道的综合施工技术 。
Kuanlunshan tunnel on Qingzang railway is a typical one that passes through frozen plateau soil. During its construction, there are many difficulties encountered such as frozen plateau soil, extremely cold, lack of oxygen, low air pressure and partial pressure of low oxygen. In the paper the general construction technology for the tunnel is introduced, including: machinery, ventilation, wet sprayed concrete, walking bridge for invert construction, waterproof and drainage system, heat insulation layer, rapid hardening and durable concrete under low temperature, oxygen supply, health monitor, and so on, which can be referred to by the similar projects.
