摘要
冻土地区路基冻融病害的整治,一直被视为世界性的难题。现有的常规施工工艺和方法在冻土地区均存在着一定的局限性。土工格栅凭借其独特的网状结构和镶嵌咬合能力,在国内外岩土工程中得到了广泛的应用。本文基于土工格栅的加筋特性和现有的格栅加筋工程的实际经验,建议可选择土工格栅可对冻土路基冻融灾害进行防治,并分别针对冻土地区常见的冻胀、融沉及翻浆灾害问题,从理论研究和工程实践方面阐述了其具有一定的实际应用性,并对其进行了应用展望。
It is a worldwide problem that the treatment about the freeze-thaw disaster of subgrade in frozen soil region. Moreover,this disaster happened in seasonal frozen regions is bigger than that happened in the perma-frost regions. General construction technologies and treatments to subgrade in permafrost region are not suit for the seasonal frost region. The geogrid is widely used in geotechnical engineering projects, because of its net structure and mosaic capacity. Based on reinforced characters of geogrid and the performance of geogrid-rein-forced earth structure in permafrost regions, this paper proposes that geogrid could be chosen to treating the frost heaving,thaw settlement and frost boiling,then the feasibility is also discussed mainly from practical engi-neering and theoretical research in detail.
