青藏铁路将通过青藏高原连续多年冻土地区 ,高原多年冻土地区发育有特殊的不良地质现象 ,如厚层地下冰、热融滑坍、热融沉陷或热融湖 (塘 )、沼泽化湿地、冰锥、冰丘和爆炸性充水鼓丘、融冻泥流等。如果处理不当 ,将对青藏铁路建设带来大量的工程技术难题 The Qinghai-Tibet Railway will develop special adverse geological phenomena through continuous permafrost areas in the Qinghai-Tibet Plateau and permafrost areas in the plateau, such as thick underground ice, slump of thermal melting, thermal melting and subsidence or hot-melt lakes (ponds) and swamp wetlands , Ice cones, ice hurricane and explosive water filled drum mound, frozen mud flow. If handled improperly, it will bring a lot of engineering and technical problems to the Qinghai-Tibet Railway
