Mongolia is a land-locked country in Central Asia, located between Russia and China. The country's high altitude results in cold, dry and harsh climatic conditions with permafrost being widespread through the territory. Permafrost is spread on 63.0 percent of the territory of Mongolia. Although the capital city Ulaanbaatar is sited on area with discontinuous permafrost, in next 10 years projects such as a university campus, a logistics center, “New Nalaikh” residential block and the extension of railway and highway connecting Russia and China have been planned. Engineering-geological and geotechnical studies have been conducted for these construction projects. This paper emphasizes that the main conditions of permafrost existence are the climate and geocrylogical location. Regional classification of permafrost areas, in order to select optimal principle of foundation design have been suggested based on the many years of experience and lessons learned from construction works in Mongolian geotechnical and climatic conditions.
