解放以来,随着森林资源的开发,我国东北大兴安岭多年冻土及严寒地区,新建铁路不断向林区纵深延展。廿多年来,我们在近两千公里新线铁路勘测过程中,一共进行了水文地质勘测近200个站点,掌握和积累了较多的调查和勘探资料。通过资料整理、分析、对比,对这一地区的水文地质特点有了初步的认识和了解,现在进行一次总结。由于水平所限,欠妥之处一定很多,希望同志门不吝指正。 Since the liberation, with the development of forest resources, the permafrost in the Daxinganling Mountains in northeast China and the severe cold areas have continuously extended the newly-built railways to the forest areas. Over the past 20 years, we conducted nearly 200 sites for hydrogeological surveys during the survey of nearly 2,000 km of new railway line. We have mastered and accumulated more survey and exploration data. Through data collation, analysis, comparison, preliminary understanding and understanding of the hydrogeological features of the area, now a summary. Due to the limited level, there must be a lot of defects, I hope the door will not hesitate to correct me.
