| Xinjiang has a large area with a remarkable difference between climate, topography and geology. With more and more investment in the highway construction of Western China, at present, the second rank division and design parameter can't reflect the difference between highway engineering constructions of the same rank zone in Xinjiang. Based on the researching thesis of the third rank natural division for highway in Xinjiang and environment parameter, through collecting enoumous datum, the thesis analysize the natural conditions, highway construction characters and effecting factors of natural conditions to highway engineering, an so on; put forward the highway design parameter of Xinjiang: the modulus of resilience of roadbed soid-Eo and California bearing ratio-CBR, based on the third rank division; express synthetecally the effection of the natural conditions to highway construction, through various forms such as characters, forms and etc. |
