我国冻土路基工程研究的过去、现在和未来

回顾了中国冻土路基研究发展历程中的重要成果和历史脉络,重点介绍了青藏高原路基工程方面所取得的重要成果.随着国家西部大开发战略的实施和青藏铁路丁程的建设,我国在冻土路基基础理论、路基稳定性技术和理论模型和模拟等领域取得了重要进展.研究队伍迅速成长,特别是在冻土路基设计原则和理念的创新和进步世界瞩目,为将青藏铁路建设成世界一流的高原铁路奠定了坚实的理论基础.同时,青藏铁路的建设为如何修筑多年冻土路基提供了广阔的试验平台,不论从冻土路基设计理论、计算理论、路基稳定性技术等方面;还是新材料、新技术使用方面都可使冻土区路基修筑技术发展迈上一个新台阶.最后,基于冻土路基工程研究的实际和未来国家需求,提出了本学科未来的研究方向和需重点关注之处.

The Frozen Ground Roadbed Researches in China:Past,Present and Future

The great achievements and progresses in frozen ground roadbed researches since the new China foundation were reviewed,and especially,the research works of the Qinghai-Tibet highway research group were focused to introduce.With the development of the west of China and the engineering construction in cold regions,significant progress in theories,embankment stability technologies and numerical models were made,which all became the base of Qinghai-Tibet Railway construction.At the same time,the Qinghai-Tibet R...
