Abstract For the protection of lithical side slope caused by cutting mountainous body,some traditional measures such as mortar protection and so on,have always been used in constructing the expressway,which results in the ecological vegetation to be unable to restore along the route.In this paper,as an example of a section from Linxiang to Changsha of Jingzhu Expressway to be briefly called as Linchang expressway,an external-soil spray seeding technique to unite with engineering measures and ecological protection has successively been(developed)by testing in the field,of which the applying effects are satisfied through Linchang expressway.The external-soil spray seeding technique has great significance for changing from traditional engineering measures to softly ecological protection.
