Abstract Research purposes: Qingzang railway locates in the hinterland of Qingzang altiplano, it has special natural and geological condition. Enhancing the study of geological problems in construction, optimizing and consummating the designation were essential demand for constructing the best railway of frozen earth of altiplano in the world.
Research methods: Linked with construction, we take local inspection time after time and winter callback. Aimed to the problems, we do essential convey, test and subject research, demonstrated cause and feature of harming engineering to set down the viable measure of managing.
Research results: The paper finds out new engineering geological problems while construction of railway. The established treatment measure was viable and its effect was better.
Research Conclusions: The cause of appearing new engineering geological problem in construction of Qingzang railway was special climate condition, the change of tiny landform, sand blown by wind, surface water and underground water flowing, which were all caused by railway construction. It was important tache for ensuring qualification of engineering construction to strengthen construction geology, dynamically design and optimize enhancing intension.
