Sustained Development of Highway Under Vulnerable Environment in Tibetan Plateau

In Tibetan Plateau, the fragile ecological environment and the frequent natural disaster result in much dangers in highway construction. The anti-disaster ability of highway system is very vulnerable. The frailty of ecological environment and the vulnerability of highway system form the principal contradiction in the Tibetan highway development. Therefore, we must increase anti-disaster ability of the highway system by rebuild and take effective measures to reduce the bad environmental influence of engineering construction in order to achieve the sustained development of highway construction.
