中文摘要
        冰冻圈与气候变化、人类工程活动和社会经济发展具有极为密切的关系,冰冻圈变化及其引发的冰冻圈灾害使寒区工程建设和安全运营面临着巨大的挑战。冰冻圈各要素对重大工程影响具有显著不同的特点,冰川、积雪、海(河、湖)冰等主要以灾害方式影响重大工程的建设、安全运营和服役性。冻土作为工程构筑物的特殊地基土,冻融灾害和冻土热力学稳定性变化均会直接影响工程的稳定性。随着全球气候环境变化,冰冻圈各要素变化及其水文、生态环境、地表过程等变化均对重大工程产生显著的影响,需加强重大工程建设和安全运营与环境因素变化之间关系研究,重大工程安全保障技术也需更加综合地考虑气候和环境变化的影响。因此,气候和环境变化将成为未来冰冻圈区重大工程建设、安全运营和工程服役性必须考虑的重要因素。同时,"一带一路"基础设施建设不仅给冰冻圈工程学带来机遇,而且也使其面临更大的挑战。
英文摘要
        The cryosphere is closely related to climate change, human engineering activities and social and economic development. Each element of cryosphere has significantly different influence characteristics on engineering. Disasters by glaciers, snow cover, and sea (river and lake) ice will mainly affect the construction, safe operation, and serviceability of engineering. Frozen soil is a special foundation soil for engineering structures, thus freezing-thawing disasters and thermal and mechanical stability change of frozen soil will directly affect the stability of engineering. As global change, the elements of cryosphere change and its hydrological and ecological environment, surface process changes have significant influence on engineering, thus it is needed to strengthen the relationship research between the engineering construction and safety operation and the environmental factors change. In addition, engineering security technology is also needed to be more comprehensive to consider the influence of climate and environment changes. Therefore, climate and environmental change will become an important factor to be considered in the construction, safe operation, and serviceability of engineering in the regions of cryosphere in the future. At the same time, the Belt and Road infrastructure construction not only brings opportunities to cryosphere engineering, but also faces greater challenges.
