摘　　要：对于因山体开挖形成的路堑石质边坡的防护,工程界长期以来一直采用诸如浆砌片石护坡等传统措施,使高速公路沿线被破坏的植被无法得到恢复。以京珠高速湖南省临湘至长沙段高速公路为例,通过现场试验,成功地研究开发了一种兼顾工程防护和生态环保功能于一体的石质边坡客土喷播生态防护技术,并在临长高速公路进行大面积推广应用,取得了令人满意的效果。这对改变石质边坡传统的防护措施为柔性的生态防护形式具有重要的现实意义。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 developedby 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.
