| Abstract: | At first, the forming conditions and developing characteristics of several kinds of typical harmful features related to frozen ground are discussed in the paper, such as flooding ice, icing mound, frost mound, thick ground ice, thaw slumping, thermokarst lake and swampland. Secondly, the investigating results of new harmful permafrost features in winter along Qinghai-Tibet Railway are analysed and summarized. Lastly, some data and suggestions will be provided to designing and construction departments. |
