Abstract

Abstract: Due to the bad engineering geological condition of permafrost regions in the Qinghai-Tibet Plateau, immeasurable economic and technical problems are brought for Qinghai-Tibet DC transmission engineering. Ground temperature and deformation of eight sites and ten tower foundations with different soil types and foundation forms and thermal probes treatment were monitored and measured, the change laws and influential factor of ground temperature and deformation for tower foundation is analyzed, and also long-term stability is predicted in this paper based on the monitoring results, which provides data for design and stability analysis of tower foundation in permafrost regions.

Key words: Qinghai-Tibet DC transmission engineering, permafrost regions, tower foundation, ground temperature, deformation
