| Abstract: | The 219 national highway connecting Xinjiang and Tibet passes through Arcsaiqin basin.The tectonic evolution and lithofacies zonation of sedimentation of this Cenozoic alp and lake basin are studied.Based on the results from geological investigation,drilling,geophysical prospecting and test,the special soils in the range of highway construction,like the type and degree of salinization,the expanding property of salinized soil,and the types and melting character of frozen earth as well as the salinization of frozen earth are studied.The effect of these special soils on the highway project is synthetically evaluated.Suggestion about the routine selection of reconstructed highway and the design of roadbed are given.The economical and practical measures to the treatment of the special soils are brought forward. |
