A review of recent frozen soil engineering in permafrost regions along Qinghai‐Tibet Highway, China

The nature of frozen soil research along the Qinghai‐Tibet Highway between 1993 and 2000 is systemically reviewed. Recent studies involve the engineering geology of frozen soil, the study of ground temperatures under the roadbed and the influence of the frozen soil environment, the engineering classification of frozen soils, and the use of geographical information systems. This research will materially assist in the construction of the Qinghai‐Tibet Railway.
