摘要
高原、严寒条件下的青藏铁路昆仑山隧道施工,在多年冻土隧道施工技术、合理支护结构形式以及人员健康等方面提出了严峻挑战。采用适用高原严寒条件下的施工方案,以及综合利用、保护冻土围岩的隧道施工方法和独特的通风、供暖、供氧和供水等辅助施工作业措施,保证了隧道施工的顺利进行。
The Kunlun Mountain Tunnel construction of Qinghai-Tibet Railway under the condition of plateau severe cold has presented serious challenges in view of ever-frozen ground tunnel construction technology,reasonable supporting structure forms and personnel health,etc.Appropriate construction plan applicable for the condition of the plateau severe cold was adopted in combination with the tunnel construction methods that comprehensively utilizes and protects frozen surrounding rock and the unique construction assisting measures in view of ventilating,heating,oxygen and water supply,etc.to ensure the successful construction of the tunnel.
