摘要
青藏铁路风火山隧道是世界上海拔最高多年冻土隧道,洞身全部位于冻岩之中。针对高海拔的地形和地质构造变化无常,缺氧的气候特殊条件,介绍青藏铁路隧道、桥梁桩基成孔,路基机械设备配置的原理及配套方案,充分发挥机械化作业的优势,达到科学经济的目的。
Fenghuo Hill tunnel in Qingzang Railway is the tunnel of the highest elevation in the world. Its whole body is in frozen soil of many years. The geological structure is varied and the climate is short of orygen. The hole formation of pile foundation of tunnels and bridges as well as the principle and scheme of disposal of machineries and equipments are introduced and the advantages of machanize is showed.
