Abstract: As required by the construction of Qinghai-Xizang asphalt highway, we had compiled an ice content map of permafrost along Qinghai-Xizang Highway (from Xieshui He to Tanggula Shan, about 420 km long). The mpa constists of a longtitudinal section map at the scale of 1 : 5000 and a plane map at the scale of 1:2000. This paper briefly relates the principle of compilating the maps.Permafrost is classified into five ice content types on the basis of its water content (according to percent of dry soil weight), and the thaw-settlement coefficients of each type for all the distinguished varieties are given for prediction of possible changes after construction. Based on the ice content type within the depth from o to 1 m below permafrost table, four kinds of road section are distinguished. Permafrost protective measures for each kind of section are also presented.
