Abstract:

Climate change has led to rapid cryosphere changes in the Qinghai-Xizang Plateau, resulting in the increasing of the scale and frequency of cryosphere disasters. Consequently, cryosphere changes impose considerable threaten to the engineering safety, impacting the regional sustainable development and people’s well-being in the Qinghai-Xizang Plateau. This paper reviews the challenges faced by engineering in the cryosphere regions of Qinghai-Xizang Plateau, and expounds the cryosphere changes in recent years and its future change trends. From the perspective of the types of cryosphere disasters and the observed influence of cryosphere disasters on engineering, the influence of cryosphere disasters caused by cryosphere changes on engineering design and safe operation, as well as the economic cost of engineering construction and maintenance are discussed. The coping strategies to mitigate the cryosphere changes and disasters under climate change are put forward, and the coping strategies and technical measures of engineering are discussed.

Key words: Cryosphere change, Cryosphere disaster, Engineering, Qinghai-Xizang Plateau
