| 摘 要： | 青藏铁路横穿处于强构造活动区和高寒环境的青藏高原,具有复杂的工程地质条件,不仅发育冻土和融冻灾害,而且穿越不同性质的活动断裂.本文分析了铁路经过的当雄-羊八井活动构造带的基本特征,讨论了其对铁路可能产生的严重影响.铁路的开通是工程建设的巨大成就,但是否真正解决了这些地质难题,还有待铁路长期运营的实践和考验.

| Abstract: | The Qing-Zang Railway crosses the Qinghai-Tibet plateau,in which there are many active tectonic belts.With frozen earth and varied active faults,it is very cold and has very complex mechanic geological conditions.In this paper,the author analyzed the basic characteristics of the Damxung-Yangbajain active tectonic zone and discusses the probable geological hazards.The Qing-Zang Railway is a great achievement in engineering and construction,but it should experience all sorts of geological trials during its long operation. |
