| Abstract: | Based on investigations and explorations on the permafrost engineering geological conditions and characteristics along the Qinghai-Tibet Railway, the reasonable line location and reliable engineering types have been determined for the Qinghai-Tibet Railway on permafrost regions. The research results from five different experiment-engineering sections have been used to direct designs and constructions of the railway engineering. Based on a systematic summary of the researches and practices in permafrost engineering in the Qinghai-Tibet Railway for four years, the design philosophy of !active cooling, cooling foundation and protecting frozen soils" have been put forward and the whole-measures of the roadbeds, bridges, caves and tunnels have been constituted to ensure the stability of permafrost engineering in the Qinghai-Tibet Railway. |
